| systemd System and Service Manager |
| |
| CHANGES WITH 198: |
| |
| * Configuration of unit files may now be extended via drop-in |
| files without having to edit/override the unit files |
| themselves. More specifically, if the administrator wants to |
| change one value for a service file foobar.service he can |
| now do so by dropping in a configuration snippet into |
| /etc/systemd/systemd/foobar.service.d/*.conf. The unit logic |
| will load all these snippets and apply them on top of the |
| main unit configuration file, possibly extending or |
| overriding its settings. Using these drop-in snippets is |
| generally nicer than the two earlier options for changing |
| unit files locally: copying the files from |
| /usr/lib/systemd/system/ to /etc/systemd/system/ and editing |
| them there; or creating a new file in /etc/systemd/system/ |
| that incorporates the original one via ".include". Drop-in |
| snippets into these .d/ directories can be placed in any |
| directory systemd looks for units in, and the usual |
| overriding semantics between /usr/lib, /etc and /run apply |
| for them too. |
| |
| * Most unit file settings which take lists of items can now be |
| reset by assigning the empty string to them. For example, |
| normally, settings such as Environment=FOO=BAR append a new |
| environment variable assignment to the environment block, |
| each time they are used. By assigning Environment= the empty |
| string the environment block can be reset to empty. This is |
| particularly useful with the .d/*.conf drop-in snippets |
| mentioned above, since this adds the ability to reset list |
| settings from vendor unit files via these drop-ins. |
| |
| * systemctl gained a new "list-dependencies" command for |
| listing the dependencies of a unit recursively. |
| |
| * Inhibitors are now honored and listed by "systemctl |
| suspend", "systemctl poweroff" (and similar) too, not only |
| GNOME. These commands will also list active sessions by |
| other users. |
| |
| * Resource limits (as exposed by the various control group |
| controllers) can now be controlled dynamically at runtime |
| for all units. More specifically, you can now use a command |
| like "systemctl set-cgroup-attr foobar.service cpu.shares |
| 2000" to alter the CPU shares a specific service gets. These |
| settings are stored persistently on disk, and thus allow the |
| administrator to easily adjust the resource usage of |
| services with a few simple commands. This dynamic resource |
| management logic is also available to other programs via the |
| bus. Almost any kernel cgroup attribute and controller is |
| supported. |
| |
| * systemd-vconsole-setup will now copy all font settings to |
| all allocated VTs, where it previously applied them only to |
| the foreground VT. |
| |
| * libsystemd-login gained the new sd_session_get_tty() API |
| call. |
| |
| * This release drops support for a few legacy or |
| distribution-specific LSB facility names when parsing init |
| scripts: $x-display-manager, $mail-transfer-agent, |
| $mail-transport-agent, $mail-transfer-agent, $smtp, |
| $null. Also, the mail-transfer-agent.target unit backing |
| this has been removed. Distributions which want to retain |
| compatibility with this should carry the burden for |
| supporting this themselves and patch support for these back |
| in, if they really need to. Also, the facilities $syslog and |
| $local_fs are now ignored, since systemd does not support |
| early-boot LSB init scripts anymore, and these facilities |
| are implied anyway for normal services. syslog.target has |
| also been removed. |
| |
| * There are new bus calls on PID1's Manager object for |
| cancelling jobs, and removing snapshot units. Previously, |
| both calls were only available on the Job and Snapshot |
| objects themselves. |
| |
| * systemd-journal-gatewayd gained SSL support. |
| |
| * The various "environment" files, such as /etc/locale.conf |
| now support continuation lines with a backslash ("\") as |
| last character in the line, similar in style (but different) |
| to how this is supported in shells. |
| |
| * For normal user processes the _SYSTEMD_USER_UNIT= field is |
| now implicitly appended to every log entry logged. systemctl |
| has been updated to filter by this field when operating on a |
| user systemd instance. |
| |
| * nspawn will now implicitly add the CAP_AUDIT_WRITE and |
| CAP_AUDIT_CONTROL capabilities to the capabilities set for |
| the container. This makes it easier to boot unmodified |
| Fedora systems in a container, which however still requires |
| audit=0 to be passed on the kernel command line. Auditing in |
| kernel and userspace is unfortunately still too broken in |
| context of containers, hence we recommend compiling it out |
| of the kernel or using audit=0. Hopefully this will be fixed |
| one day for good in the kernel. |
| |
| * nspawn gained the new --bind= and --bind-ro= parameters to |
| bind mount specific directories from the host into the |
| container. |
| |
| * nspawn will now mount its own devpts file system instance |
| into the container, in order not to leak pty devices from |
| the host into the container. |
| |
| * systemd will now read the firmware boot time performance |
| information from the EFI variables, if the used boot loader |
| supports this, and takes it into account for boot performance |
| analysis via "systemd-analyze". This is currently supported |
| only in conjunction with Gummiboot, but could be supported |
| by other boot loaders too. For details see: |
| |
| http://www.freedesktop.org/wiki/Software/systemd/BootLoaderInterface |
| |
| * A new generator has been added that automatically mounts the |
| EFI System Partition (ESP) to /boot, if that directory |
| exists, is empty, and no other file system has been |
| configured to be mounted there. |
| |
| * logind will now send out PrepareForSleep(false) out |
| unconditionally, after coming back from suspend. This may be |
| used by applications as asynchronous notification for |
| system resume events. |
| |
| * "systemctl unlock-sessions" has been added, that allows |
| unlocking the screens of all user sessions at once, similar |
| how "systemctl lock-sessions" already locked all users |
| sessions. This is backed by a new D-Bus call UnlockSessions(). |
| |
| * "loginctl seat-status" will now show the master device of a |
| seat. (i.e. the device of a seat that needs to be around for |
| the seat to be considered available, usually the graphics |
| card). |
| |
| * tmpfiles gained a new "X" line type, that allows |
| configuration of files and directories (with wildcards) that |
| shall be excluded from automatic cleanup ("aging"). |
| |
| * udev default rules set the device node permissions now only |
| at "add" events, and do not change them any longer with a |
| later "change" event. |
| |
| * The log messages for lid events and power/sleep keypresses |
| now carry a message ID. |
| |
| * We now have a substantially larger unit test suite, but this |
| continues to be work in progress. |
| |
| * udevadm hwdb gained a new --root= parameter to change the |
| root directory to operate relative to. |
| |
| * logind will now issue a background sync() request to the kernel |
| early at shutdown, so that dirty buffers are flushed to disk early |
| instead of at the last moment, in order to optimize shutdown |
| times a little. |
| |
| * A new bootctl tool has been added that is an interface for |
| certain boot loader operations. This is currently a preview |
| and is likely to be extended into a small mechanism daemon |
| like timedated, localed, hostnamed, and can be used by |
| graphical UIs to enumerate available boot options, and |
| request boot into firmware operations. |
| |
| * systemd-bootchart has been relicensed to LGPLv2.1+ to match |
| the rest of the package. It also has been updated to work |
| correctly in initrds. |
| |
| * Policykit previously has been runtime optional, and is now |
| also compile time optional via a configure switch. |
| |
| * systemd-analyze has been reimplemented in C. Also "systemctl |
| dot" has moved into systemd-analyze. |
| |
| * "systemctl status" with no further parameters will now print |
| the status of all active or failed units. |
| |
| * Operations such as "systemctl start" can now be executed |
| with a new mode "--irreversible" which may be used to queue |
| operations that cannot accidentally be reversed by a later |
| job queuing. This is by default used to make shutdown |
| requests more robust. |
| |
| * The Python API of systemd now gained a new module for |
| reading journal files. |
| |
| * A new tool kernel-install has been added that can install |
| kernel images according to the Boot Loader Specification: |
| |
| http://www.freedesktop.org/wiki/Specifications/BootLoaderSpec |
| |
| * Boot time console output has been improved to provide |
| animated boot time output for hanging jobs. |
| |
| * A new tool systemd-activate has been added which can be used |
| to test socket activation with, directly from the command |
| line. This should make it much easier to test and debug |
| socket activation in daemons. |
| |
| * journalctl gained a new "--reverse" (or -r) option to show |
| journal output in reverse order (i.e. newest line first). |
| |
| * journalctl gained a new "--pager-end" (or -e) option to jump |
| to immediately jump to the end of the journal in the |
| pager. This is only supported in conjunction with "less". |
| |
| * journalctl gained a new "--user-unit=" option, that works |
| similar to "--unit=" but filters for user units rather than |
| system units. |
| |
| * A number of unit files to ease adoption of systemd in |
| initrds has been added. This moves some minimal logic from |
| the various initrd implementations into systemd proper. |
| |
| * The journal files are now owned by a new group |
| "systemd-journal", which exists specifically to allow access |
| to the journal, and nothing else. Previously, we used the |
| "adm" group for that, which however possibly covers more |
| than just journal/log file access. This new group is now |
| already used by systemd-journal-gatewayd to ensure this |
| daemon gets access to the journal files and as little else |
| as possible. Note that "make install" will also set FS ACLs |
| up for /var/log/journal to give "adm" and "wheel" read |
| access to it, in addition to "systemd-journal" which owns |
| the journal files. We recommend that packaging scripts also |
| add read access to "adm" + "wheel" to /var/log/journal, and |
| all existing/future journal files. To normal users and |
| administrators little changes, however packagers need to |
| ensure to create the "systemd-journal" system group at |
| package installation time. |
| |
| * The systemd-journal-gatewayd now runs as unprivileged user |
| systemd-journal-gateway:systemd-journal-gateway. Packaging |
| scripts need to create these system user/group at |
| installation time. |
| |
| * timedated now exposes a new boolean property CanNTP that |
| indicates whether a local NTP service is available or not. |
| |
| * systemd-detect-virt will now also detect xen PVs |
| |
| * The pstore file system is now mounted by default, if it is |
| available. |
| |
| * In addition to the SELinux and IMA policies we will now also |
| load SMACK policies at early boot. |

| CHANGES WITH 197: |
| |
| * Timer units now support calendar time events in addition to |
| monotonic time events. That means you can now trigger a unit |
| based on a calendar time specification such as "Thu,Fri |
| 2013-*-1,5 11:12:13" which refers to 11:12:13 of the first |
| or fifth day of any month of the year 2013, given that it is |
| a thursday or friday. This brings timer event support |
| considerably closer to cron's capabilities. For details on |
| the supported calendar time specification language see |
| systemd.time(7). |
| |
| * udev now supports a number of different naming policies for |
| network interfaces for predictable names, and a combination |
| of these policies is now the default. Please see this wiki |
| document for details: |
| |
| http://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames |
| |
| * Auke Kok's bootchart implementation has been added to the |
| systemd tree. It's an optional component that can graph the |
| boot in quite some detail. It's one of the best bootchart |
| implementations around and minimal in its code and |
| dependencies. |
| |
| * nss-myhostname has been integrated into the systemd source |
| tree. nss-myhostname guarantees that the local hostname |
| always stays resolvable via NSS. It has been a weak |
| requirement of systemd-hostnamed since a long time, and |
| since its code is actually trivial we decided to just |
| include it in systemd's source tree. It can be turned off |
| with a configure switch. |
| |
| * The read-ahead logic is now capable of properly detecting |
| whether a btrfs file system is on SSD or rotating media, in |
| order to optimize the read-ahead scheme. Previously, it was |
| only capable of detecting this on traditional file systems |
| such as ext4. |
| |
| * In udev, additional device properties are now read from the |
| IAB in addition to the OUI database. Also, Bluetooth company |
| identities are attached to the devices as well. |
| |
| * In service files %U may be used as specifier that is |
| replaced by the configured user name of the service. |
| |
| * nspawn may now be invoked without a controlling TTY. This |
| makes it suitable for invocation as its own service. This |
| may be used to set up a simple containerized server system |
| using only core OS tools. |
| |
| * systemd and nspawn can now accept socket file descriptors |
| when they are started for socket activation. This enables |
| implementation of socket activated nspawn |
| containers. i.e. think about autospawning an entire OS image |
| when the first SSH or HTTP connection is received. We expect |
| that similar functionality will also be added to libvirt-lxc |
| eventually. |
| |
| * journalctl will now suppress ANSI color codes when |
| presenting log data. |
| |
| * systemctl will no longer show control group information for |
| a unit if a the control group is empty anyway. |
| |
| * logind can now automatically suspend/hibernate/shutdown the |
| system on idle. |
| |
| * /etc/machine-info and hostnamed now also expose the chassis |
| type of the system. This can be used to determine whether |
| the local system is a laptop, desktop, handset or |
| tablet. This information may either be configured by the |
| user/vendor or is automatically determined from ACPI and DMI |
| information if possible. |
| |
| * A number of PolicyKit actions are now bound together with |
| "imply" rules. This should simplify creating UIs because |
| many actions will now authenticate similar ones as well. |
| |
| * Unit files learnt a new condition ConditionACPower= which |
| may be used to conditionalize a unit depending on whether an |
| AC power source is connected or not, of whether the system |
| is running on battery power. |
| |
| * systemctl gained a new "is-failed" verb that may be used in |
| shell scripts and suchlike to check whether a specific unit |
| is in the "failed" state. |
| |
| * The EnvironmentFile= setting in unit files now supports file |
| globbing, and can hence be used to easily read a number of |
| environment files at once. |
| |
| * systemd will no longer detect and recognize specific |
| distributions. All distribution-specific #ifdeffery has been |
| removed, systemd is now fully generic and |
| distribution-agnostic. Effectively, not too much is lost as |
| a lot of the code is still accessible via explicit configure |
| switches. However, support for some distribution specific |
| legacy configuration file formats has been dropped. We |
| recommend distributions to simply adopt the configuration |
| files everybody else uses now and convert the old |
| configuration from packaging scripts. Most distributions |
| already did that. If that's not possible or desirable, |
| distributions are welcome to forward port the specific |
| pieces of code locally from the git history. |
| |
| * When logging a message about a unit systemd will now always |
| log the unit name in the message meta data. |
| |
| * localectl will now also discover system locale data that is |
| not stored in locale archives, but directly unpacked. |
| |
| * logind will no longer unconditionally use framebuffer |
| devices as seat masters, i.e. as devices that are required |
| to be existing before a seat is considered preset. Instead, |
| it will now look for all devices that are tagged as |
| "seat-master" in udev. By default framebuffer devices will |
| be marked as such, but depending on local systems other |
| devices might be marked as well. This may be used to |
| integrate graphics cards using closed source drivers (such |
| as NVidia ones) more nicely into logind. Note however, that |
| we recommend using the open source NVidia drivers instead, |
| and no udev rules for the closed-source drivers will be |
| shipped from us upstream. |

| CHANGES WITH 196: |
| |
| * udev gained support for loading additional device properties |
| from an indexed database that is keyed by vendor/product IDs |
| and similar device identifiers. For the beginning this |
| "hwdb" is populated with data from the well-known PCI and |
| USB database, but also includes PNP, ACPI and OID data. In |
| the longer run this indexed database shall grow into |
| becoming the one central database for non-essential |
| userspace device metadata. Previously, data from the PCI/USB |
| database was only attached to select devices, since the |
| lookup was a relatively expensive operation due to O(n) time |
| complexity (with n being the number of entries in the |
| database). Since this is now O(1), we decided to add in this |
| data for all devices where this is available, by |
| default. Note that the indexed database needs to be rebuilt |
| when new data files are installed. To achieve this you need |
| to update your packaging scripts to invoke "udevadm hwdb |
| --update" after installation of hwdb data files. For |
| RPM-based distributions we introduced the new |
| %udev_hwdb_update macro for this purpose. |
| |
| * The Journal gained support for the "Message Catalog", an |
| indexed database to link up additional information with |
| journal entries. For further details please check: |
| |
| http://www.freedesktop.org/wiki/Software/systemd/catalog |
| |
| The indexed message catalog database also needs to be |
| rebuilt after installation of message catalog files. Use |
| "journalctl --update-catalog" for this. For RPM-based |
| distributions we introduced the %journal_catalog_update |
| macro for this purpose. |
| |
| * The Python Journal bindings gained support for the standard |
| Python logging framework. |
| |
| * The Journal API gained new functions for checking whether |
| the underlying file system of a journal file is capable of |
| properly reporting file change notifications, or whether |
| applications that want to reflect journal changes "live" |
| need to recheck journal files continously in appropriate |
| time intervals. |
| |
| * It is now possible to set the "age" field for tmpfiles |
| entries to 0, indicating that files matching this entry |
| shall always be removed when the directories are cleaned up. |
| |
| * coredumpctl gained a new "gdb" verb which invokes gdb |
| right-away on the selected coredump. |
| |
| * There's now support for "hybrid sleep" on kernels that |
| support this, in addition to "suspend" and "hibernate". Use |
| "systemctl hybrid-sleep" to make use of this. |
| |
| * logind's HandleSuspendKey= setting (and related settings) |
| now gained support for a new "lock" setting to simply |
| request the screen lock on all local sessions, instead of |
| actually executing a suspend or hibernation. |
| |
| * systemd will now mount the EFI variables file system by |
| default. |
| |
| * Socket units now gained support for configuration of the |
| SMACK security label. |
| |
| * timedatectl will now output the time of the last and next |
| daylight saving change. |
| |
| * We dropped support for various legacy and distro-specific |
| concepts, such as insserv, early-boot SysV services |
| (i.e. those for non-standard runlevels such as 'b' or 'S') |
| or ArchLinux /etc/rc.conf support. We recommend the |
| distributions who still need support this to either continue |
| to maintain the necessary patches downstream, or find a |
| different solution. (Talk to us if you have questions!) |
| |
| * Various systemd components will now bypass PolicyKit checks |
| for root and otherwise handle properly if PolicyKit is not |
| found to be around. This should fix most issues for |
| PolicyKit-less systems. Quite frankly this should have been |
| this way since day one. It is absolutely our intention to |
| make systemd work fine on PolicyKit-less systems, and we |
| consider it a bug if something doesn't work as it should if |
| PolicyKit is not around. |
| |
| * For embedded systems it is now possible to build udev and |
| systemd without blkid and/or kmod support. |
| |
| * "systemctl switch-root" is now capable of switching root |
| more than once. I.e. in addition to transitions from the |
| initrd to the host OS it is now possible to transition to |
| further OS images from the host. This is useful to implement |
| offline updating tools. |
| |
| * Various other additions have been made to the RPM macros |
| shipped with systemd. Use %udev_rules_update() after |
| installing new udev rules files. %_udevhwdbdir, |
| %_udevrulesdir, %_journalcatalogdir, %_tmpfilesdir, |
| %_sysctldir are now available which resolve to the right |
| directories for packages to place various data files in. |
| |
| * journalctl gained the new --full switch (in addition to |
| --all, to disable ellipsation for long messages. |

| CHANGES WITH 195: |
| |
| * journalctl gained new --since= and --until= switches to |
| filter by time. It also now supports nice filtering for |
| units via --unit=/-u. |
| |
| * Type=oneshot services may use ExecReload= and do the |
| right thing. |
| |
| * The journal daemon now supports time-based rotation and |
| vacuuming, in addition to the usual disk-space based |
| rotation. |
| |
| * The journal will now index the available field values for |
| each field name. This enables clients to show pretty drop |
| downs of available match values when filtering. The bash |
| completion of journalctl has been updated |
| accordingly. journalctl gained a new switch -F to list all |
| values a certain field takes in the journal database. |
| |
| * More service events are now written as structured messages |
| to the journal, and made recognizable via message IDs. |
| |
| * The timedated, localed and hostnamed mini-services which |
| previously only provided support for changing time, locale |
| and hostname settings from graphical DEs such as GNOME now |
| also have a minimal (but very useful) text-based client |
| utility each. This is probably the nicest way to changing |
| these settings from the command line now, especially since |
| it lists available options and is fully integrated with bash |
| completion. |
| |
| * There's now a new tool "systemd-coredumpctl" to list and |
| extract coredumps from the journal. |
| |
| * We now install a README each in /var/log/ and |
| /etc/rc.d/init.d explaining where the system logs and init |
| scripts went. This hopefully should help folks who go to |
| that dirs and look into the otherwise now empty void and |
| scratch their heads. |
| |
| * When user-services are invoked (by systemd --user) the |
| $MANAGERPID env var is set to the PID of systemd. |
| |
| * SIGRTMIN+24 when sent to a --user instance will now result |
| in immediate termination of systemd. |
| |
| * gatewayd received numerous feature additions such as a |
| "follow" mode, for live syncing and filtering. |
| |
| * browse.html now allows filtering and showing detailed |
| information on specific entries. Keyboard navigation and |
| mouse screen support has been added. |
| |
| * gatewayd/journalctl now supports HTML5/JSON |
| Server-Sent-Events as output. |
| |
| * The SysV init script compatibility logic will now |
| heuristically determine whether a script supports the |
| "reload" verb, and only then make this available as |
| "systemctl reload". |
| |
| * "systemctl status --follow" has been removed, use "journalctl |
| -u" instead. |
| |
| * journald.conf's RuntimeMinSize=, PersistentMinSize= settings |
| have been removed since they are hardly useful to be |
| configured. |
| |
| * And I'd like to take the opportunity to specifically mention |
| Zbigniew for his great contributions. Zbigniew, you rock! |

| CHANGES WITH 194: |
| |
| * If /etc/vconsole.conf is non-existent or empty we will no |
| longer load any console font or key map at boot by |
| default. Instead the kernel defaults will be left |
| intact. This is definitely the right thing to do, as no |
| configuration should mean no configuration, and hard-coding |
| font names that are different on all archs is probably a bad |
| idea. Also, the kernel default key map and font should be |
| good enough for most cases anyway, and mostly identical to |
| the userspace fonts/key maps we previously overloaded them |
| with. If distributions want to continue to default to a |
| non-kernel font or key map they should ship a default |
| /etc/vconsole.conf with the appropriate contents. |

| CHANGES WITH 193: |
| |
| * journalctl gained a new --cursor= switch to show entries |
| starting from the specified location in the journal. |
| |
| * We now enforce a size limit on journal entry fields exported |
| with "-o json" in journalctl. Fields larger than 4K will be |
| assigned null. This can be turned off with --all. |
| |
| * An (optional) journal gateway daemon is now available as |
| "systemd-journal-gatewayd.service". This service provides |
| access to the journal via HTTP and JSON. This functionality |
| will be used to implement live log synchronization in both |
| pull and push modes, but has various other users too, such |
| as easy log access for debugging of embedded devices. Right |
| now it is already useful to retrieve the journal via HTTP: |
| |
| # systemctl start systemd-journal-gatewayd.service |
| # wget http://localhost:19531/entries |
| |
| This will download the journal contents in a |
| /var/log/messages compatible format. The same as JSON: |
| |
| # curl -H"Accept: application/json" http://localhost:19531/entries |
| |
| This service is also accessible via a web browser where a |
| single static HTML5 app is served that uses the JSON logic |
| to enable the user to do some basic browsing of the |
| journal. This will be extended later on. Here's an example |
| screenshot of this app in its current state: |

| |
| CHANGES WITH 192: |
| |
| * The bash completion logic is now available for journalctl |
| too. |
| |
| * We don't mount the "cpuset" controller anymore together with |
| "cpu" and "cpuacct", as "cpuset" groups generally cannot be |
| started if no parameters are assigned to it. "cpuset" hence |
| broke code that assumed it it could create "cpu" groups and |
| just start them. |
| |
| * journalctl -f will now subscribe to terminal size changes, |
| and line break accordingly. |

| |
| CHANGES WITH 191: |
| |
| * nspawn will now create a symlink /etc/localtime in the |
| container environment, copying the host's timezone |
| setting. Previously this has been done via a bind mount, but |
| since symlinks cannot be bind mounted this has now been |
| changed to create/update the appropriate symlink. |
| |
| * journalctl -n's line number argument is now optional, and |
| will default to 10 if omitted. |
| |
| * journald will now log the maximum size the journal files may |
| take up on disk. This is particularly useful if the default |
| built-in logic of determining this parameter from the file |
| system size is used. Use "systemctl status |
| systemd-journald.service" to see this information. |
| |
| * The multi-seat X wrapper tool has been stripped down. As X |
| is now capable of enumerating graphics devices via udev in a |
| seat-aware way the wrapper is not strictly necessary |
| anymore. A stripped down temporary stop-gap is still shipped |
| until the upstream display managers have been updated to |
| fully support the new X logic. Expect this wrapper to be |
| removed entirely in one of the next releases. |
| |
| * HandleSleepKey= in logind.conf has been split up into |
| HandleSuspendKey= and HandleHibernateKey=. The old setting |
| is not available anymore. X11 and the kernel are |
| distuingishing between these keys and we should too. This |
| also means the inhibition lock for these keys has been split |
| into two. |

| |
| CHANGES WITH 190: |
| |
| * Whenever a unit changes state we'll now log this to the |
| journal and show along the unit's own log output in |
| "systemctl status". |
| |
| * ConditionPathIsMountPoint= can now properly detect bind |
| mount points too. (Previously, a bind mount of one file |
| system to another place in the same file system could not be |
| detected as mount, since they shared struct stat's st_dev |
| field.) |
| |
| * We will now mount the cgroup controllers cpu, cpuacct, |
| cpuset and the controllers net_cls, net_prio together by |
| default. |
| |
| * nspawn containers will now have a virtualized boot |
| ID. (i.e. /proc/sys/kernel/random/boot_id is now mounted |
| over with a randomized ID at container initialization). This |
| has the effect of making "journalctl -b" do the right thing |
| in a container. |
| |
| * The JSON output journal serialization has been updated not |
| to generate "endless" list objects anymore, but rather one |
| JSON object per line. This is more in line how most JSON |
| parsers expect JSON objects. The new output mode |
| "json-pretty" has been added to provide similar output, but |
| neatly aligned for readability by humans. |
| |
| * We dropped all explicit sync() invocations in the shutdown |
| code. The kernel does this implicitly anyway in the kernel |
| reboot() syscall. halt(8)'s -n option is now a compatibility |
| no-op. |
| |
| * We now support virtualized reboot() in containers, as |
| supported by newer kernels. We will fall back to exit() if |
| CAP_SYS_REBOOT is not available to the container. Also, |
| nspawn makes use of this now and will actually reboot the |
| container if the containerized OS asks for that. |
| |
| * journalctl will only show local log output by default |
| now. Use --merge (-m) to show remote log output, too. |
| |
| * libsystemd-journal gained the new sd_journal_get_usage() |
| call to determine the current disk usage of all journal |
| files. This is exposed in the new "journalctl --disk-usage" |
| command. |
| |
| * journald gained a new configuration setting SplitMode= in |
| journald.conf which may be used to control how user journals |
| are split off. See journald.conf(5) for details. |
| |
| * A new condition type ConditionFileNotEmpty= has been added. |
| |
| * tmpfiles' "w" lines now support file globbing, to write |
| multiple files at once. |
| |
| * We added Python bindings for the journal submission |
| APIs. More Python APIs for a number of selected APIs will |
| likely follow. Note that we intend to add native bindings |
| only for the Python language, as we consider it common |
| enough to deserve bindings shipped within systemd. There are |
| various projects outside of systemd that provide bindings |
| for languages such as PHP or Lua. |
| |
| * Many conditions will now resolve specifiers such as %i. In |
| addition, PathChanged= and related directives of .path units |
| now support specifiers as well. |
| |
| * There's now a new RPM macro definition for the system preset |
| dir: %_presetdir. |
| |
| * journald will now warn if it can't foward a message to the |
| syslog daemon because it's socket is full. |
| |
| * timedated will no longer write or process /etc/timezone, |
| except on Debian. As we do not support late mounted /usr |
| anymore /etc/localtime always being a symlink is now safe, |
| and hence the information in /etc/timezone is not necessary |
| anymore. |
| |
| * logind will now always reserve one VT for a text getty (VT6 |
| by default). Previously if more than 6 X sessions where |
| started they took up all the VTs with auto-spawned gettys, |
| so that no text gettys were available anymore. |
| |
| * udev will now automatically inform the btrfs kernel logic |
| about btrfs RAID components showing up. This should make |
| simple hotplug based btrfs RAID assembly work. |
| |
| * PID 1 will now increase its RLIMIT_NOFILE to 64K by default |
| (but not for its children which will stay at the kernel |
| default). This should allow setups with a lot more listening |
| sockets. |
| |
| * systemd will now always pass the configured timezone to the |
| kernel at boot. timedated will do the same when the timezone |
| is changed. |
| |
| * logind's inhibition logic has been updated. By default, |
| logind will now handle the lid switch, the power and sleep |
| keys all the time, even in graphical sessions. If DEs want |
| to handle these events on their own they should take the new |
| handle-power-key, handle-sleep-key and handle-lid-switch |
| inhibitors during their runtime. A simple way to achiveve |
| that is to invoke the DE wrapped in an invocation of: |
| |
| systemd-inhibit --what=handle-power-key:handle-sleep-key:handle-lid-switch ... |
| |
| * Access to unit operations is now checked via SELinux taking |
| the unit file label and client process label into account. |
| |
| * systemd will now notify the administrator in the journal |
| when he over-mounts a non-empty directory. |
| |
| * There are new specifiers that are resolved in unit files, |
| for the host name (%H), the machine ID (%m) and the boot ID |
| (%b). |

| CHANGES WITH 189: |
| |
| * Support for reading structured kernel messages from |
| /dev/kmsg has now been added and is enabled by default. |
| |
| * Support for reading kernel messages from /proc/kmsg has now |
| been removed. If you want kernel messages in the journal |
| make sure to run a recent kernel (>= 3.5) that supports |
| reading structured messages from /dev/kmsg (see |
| above). /proc/kmsg is now exclusive property of classic |
| syslog daemons again. |
| |
| * The libudev API gained the new |
| udev_device_new_from_device_id() call. |
| |
| * The logic for file system namespace (ReadOnlyDirectory=, |
| ReadWriteDirectoy=, PrivateTmp=) has been reworked not to |
| require pivot_root() anymore. This means fewer temporary |
| directories are created below /tmp for this feature. |
| |
| * nspawn containers will now see and receive all submounts |
| made on the host OS below the root file system of the |
| container. |
| |
| * Forward Secure Sealing is now supported for Journal files, |
| which provide cryptographical sealing of journal files so |
| that attackers cannot alter log history anymore without this |
| being detectable. Lennart will soon post a blog story about |
| this explaining it in more detail. |
| |
| * There are two new service settings RestartPreventExitStatus= |
| and SuccessExitStatus= which allow configuration of exit |
| status (exit code or signal) which will be excepted from the |
| restart logic, resp. consider successful. |
| |
| * journalctl gained the new --verify switch that can be used |
| to check the integrity of the structure of journal files and |
| (if Forward Secure Sealing is enabled) the contents of |
| journal files. |
| |
| * nspawn containers will now be run with /dev/stdin, /dev/fd/ |
| and similar symlinks pre-created. This makes running shells |
| as container init process a lot more fun. |
| |
| * The fstab support can now handle PARTUUID= and PARTLABEL= |
| entries. |
| |
| * A new ConditionHost= condition has been added to match |
| against the hostname (with globs) and machine ID. This is |
| useful for clusters where a single OS image is used to |
| provision a large number of hosts which shall run slightly |
| different sets of services. |
| |
| * Services which hit the restart limit will now be placed in a |
| failure state. |

| |
| CHANGES WITH 188: |
| |
| * When running in --user mode systemd will now become a |
| subreaper (PR_SET_CHILD_SUBREAPER). This should make the ps |
| tree a lot more organized. |
| |
| * A new PartOf= unit dependency type has been introduced that |
| may be used to group services in a natural way. |
| |
| * "systemctl enable" may now be used to enable instances of |
| services. |
| |
| * journalctl now prints error log levels in red, and |
| warning/notice log levels in bright white. It also supports |
| filtering by log level now. |
| |
| * cgtop gained a new -n switch (similar to top), to configure |
| the maximum number of iterations to run for. It also gained |
| -b, to run in batch mode (accepting no input). |
| |
| * The suffix ".service" may now be ommited on most systemctl |
| command lines involving service unit names. |
| |
| * There's a new bus call in logind to lock all sessions, as |
| well as a loginctl verb for it "lock-sessions". |
| |
| * libsystemd-logind.so gained a new call sd_journal_perror() |
| that works similar to libc perror() but logs to the journal |
| and encodes structured information about the error number. |
| |
| * /etc/crypttab entries now understand the new keyfile-size= |
| option. |
| |
| * shutdown(8) now can send a (configurable) wall message when |
| a shutdown is cancelled. |
| |
| * The mount propagation mode for the root file system will now |
| default to "shared", which is useful to make containers work |
| nicely out-of-the-box so that they receive new mounts from |
| the host. This can be undone locally by running "mount |
| --make-rprivate /" if needed. |
| |
| * The prefdm.service file has been removed. Distributions |
| should maintain this unit downstream if they intend to keep |
| it around. However, we recommend writing normal unit files |
| for display managers instead. |
| |
| * Since systemd is a crucial part of the OS we will now |
| default to a number of compiler switches that improve |
| security (hardening) such as read-only relocations, stack |
| protection, and suchlike. |
| |
| * The TimeoutSec= setting for services is now split into |
| TimeoutStartSec= and TimeoutStopSec= to allow configuration |
| of individual time outs for the start and the stop phase of |
| the service. |

| CHANGES WITH 187: |
| |
| * The journal and id128 C APIs are now fully documented as man |
| pages. |
| |
| * Extra safety checks have been added when transitioning from |
| the initial RAM disk to the main system to avoid accidental |
| data loss. |
| |
| * /etc/crypttab entries now understand the new keyfile-offset= |
| option. |
| |
| * systemctl -t can now be used to filter by unit load state. |
| |
| * The journal C API gained the new sd_journal_wait() call to |
| make writing synchronous journal clients easier. |
| |
| * journalctl gained the new -D switch to show journals from a |
| specific directory. |
| |
| * journalctl now displays a special marker between log |
| messages of two different boots. |
| |
| * The journal is now explicitly flushed to /var via a service |
| systemd-journal-flush.service, rather than implicitly simply |
| by seeing /var/log/journal to be writable. |
| |
| * journalctl (and the journal C APIs) can now match for much |
| more complex expressions, with alternatives and |
| disjunctions. |
| |
| * When transitioning from the initial RAM disk to the main |
| system we will now kill all processes in a killing spree to |
| ensure no processes stay around by accident. |
| |
| * Three new specifiers may be used in unit files: %u, %h, %s |
| resolve to the user name, user home directory resp. user |
| shell. This is useful for running systemd user instances. |
| |
| * We now automatically rotate journal files if their data |
| object hash table gets a fill level > 75%. We also size the |
| hash table based on the configured maximum file size. This |
| together should lower hash collisions drastically and thus |
| speed things up a bit. |
| |
| * journalctl gained the new "--header" switch to introspect |
| header data of journal files. |
| |
| * A new setting SystemCallFilters= has been added to services |
| which may be used to apply blacklists or whitelists to |
| system calls. This is based on SECCOMP Mode 2 of Linux 3.5. |
| |
| * nspawn gained a new --link-journal= switch (and quicker: -j) |
| to link the container journal with the host. This makes it |
| very easy to centralize log viewing on the host for all |
| guests while still keeping the journal files separated. |
| |
| * Many bugfixes and optimizations |

| |
| CHANGES WITH 186: |
| |
| * Several tools now understand kernel command line arguments, |
| which are only read when run in an initial RAM disk. They |
| usually follow closely their normal counterparts, but are |
| prefixed with rd. |
| |
| * There's a new tool to analyze the readahead files that are |
| automatically generated at boot. Use: |
| |
| /usr/lib/systemd/systemd-readahead analyze /.readahead |
| |
| * We now provide an early debug shell on tty9 if this enabled. Use: |
| |
| systemctl enable debug-shell.service |
| |
| * All plymouth related units have been moved into the Plymouth |
| package. Please make sure to upgrade your Plymouth version |
| as well. |
| |
| * systemd-tmpfiles now supports getting passed the basename of |
| a configuration file only, in which case it will look for it |
| in all appropriate directories automatically. |
| |
| * udevadm info now takes a /dev or /sys path as argument, and |
| does the right thing. Example: |
| |
| udevadm info /dev/sda |
| udevadm info /sys/class/block/sda |
| |
| * systemctl now prints a warning if a unit is stopped but a |
| unit that might trigger it continues to run. Example: a |
| service is stopped but the socket that activates it is left |
| running. |
| |
| * "systemctl status" will now mention if the log output was |
| shortened due to rotation since a service has been started. |
| |
| * The journal API now exposes functions to determine the |
| "cutoff" times due to rotation. |
| |
| * journald now understands SIGUSR1 and SIGUSR2 for triggering |
| immediately flushing of runtime logs to /var if possible, |
| resp. for triggering immediate rotation of the journal |
| files. |
| |
| * It is now considered an error if a service is attempted to |
| be stopped that is not loaded. |
| |
| * XDG_RUNTIME_DIR now uses numeric UIDs instead of usernames. |
| |
| * systemd-analyze now supports Python 3 |
| |
| * tmpfiles now supports cleaning up directories via aging |
| where the first level dirs are always kept around but |
| directories beneath it automatically aged. This is enabled |
| by prefixing the age field with '~'. |
| |
| * Seat objects now expose CanGraphical, CanTTY properties |
| which is required to deal with very fast bootups where the |
| display manager might be running before the graphics drivers |
| completed initialization. |
| |
| * Seat objects now expose a State property. |
| |
| * We now include RPM macros for service enabling/disabling |
| based on the preset logic. We recommend RPM based |
| distributions to make use of these macros if possible. This |
| makes it simpler to reuse RPM spec files across |
| distributions. |
| |
| * We now make sure that the collected systemd unit name is |
| always valid when services log to the journal via |
| STDOUT/STDERR. |
| |
| * There's a new man page kernel-command-line(7) detailing all |
| command line options we understand. |
| |
| * The fstab generator may now be disabled at boot by passing |
| fstab=0 on the kernel command line. |
| |
| * A new kernel command line option modules-load= is now understood |
| to load a specific kernel module statically, early at boot. |
| |
| * Unit names specified on the systemctl command line are now |
| automatically escaped as needed. Also, if file system or |
| device paths are specified they are automatically turned |
| into the appropriate mount or device unit names. Example: |
| |
| systemctl status /home |
| systemctl status /dev/sda |
| |
| * The SysVConsole= configuration option has been removed from |
| system.conf parsing. |
| |
| * The SysV search path is no longer exported on the D-Bus |
| Manager object. |
| |
| * The Names= option is been removed from unit file parsing. |
| |
| * There's a new man page bootup(7) detailing the boot process. |
| |
| * Every unit and every generator we ship with systemd now |
| comes with full documentation. The self-explanatory boot is |
| complete. |
| |
| * A couple of services gained "systemd-" prefixes in their |
| name if they wrap systemd code, rather than only external |
| code. Among them fsck@.service which is now |
| systemd-fsck@.service. |
| |
| * The HaveWatchdog property has been removed from the D-Bus |
| Manager object. |
| |
| * systemd.confirm_spawn= on the kernel command line should now |
| work sensibly. |
| |
| * There's a new man page crypttab(5) which details all options |
| we actually understand. |
| |
| * systemd-nspawn gained a new --capability= switch to pass |
| additional capabilities to the container. |
| |
| * timedated will now read known NTP implementation unit names |
| from /usr/lib/systemd/ntp-units.d/*.list, |
| systemd-timedated-ntp.target has been removed. |
| |
| * journalctl gained a new switch "-b" that lists log data of |
| the current boot only. |
| |
| * The notify socket is in the abstract namespace again, in |
| order to support daemons which chroot() at start-up. |
| |
| * There is a new Storage= configuration option for journald |
| which allows configuration of where log data should go. This |
| also provides a way to disable journal logging entirely, so |
| that data collected is only forwarded to the console, the |
| kernel log buffer or another syslog implementation. |
| |
| * Many bugfixes and optimizations |

| CHANGES WITH 185: |
| |
| * "systemctl help <unit>" now shows the man page if one is |
| available. |
| |
| * Several new man pages have been added. |
| |
| * MaxLevelStore=, MaxLevelSyslog=, MaxLevelKMsg=, |
| MaxLevelConsole= can now be specified in |
| journald.conf. These options allow reducing the amount of |
| data stored on disk or forwarded by the log level. |
| |
| * TimerSlackNSec= can now be specified in system.conf for |
| PID1. This allows system-wide power savings. |

| CHANGES WITH 184: |
| |
| * logind is now capable of (optionally) handling power and |
| sleep keys as well as the lid switch. |
| |
| * journalctl now understands the syntax "journalctl |
| /usr/bin/avahi-daemon" to get all log output of a specific |
| daemon. |
| |
| * CapabilityBoundingSet= in system.conf now also influences |
| the capability bound set of usermode helpers of the kernel. |

| |
| CHANGES WITH 183: |
| |
| * Note that we skipped 139 releases here in order to set the |
| new version to something that is greater than both udev's |
| and systemd's most recent version number. |
| |
| * udev: all udev sources are merged into the systemd source tree now. |
| All future udev development will happen in the systemd tree. It |
| is still fully supported to use the udev daemon and tools without |
| systemd running, like in initramfs or other init systems. Building |
| udev though, will require the *build* of the systemd tree, but |
| udev can be properly *run* without systemd. |
| |
| * udev: /lib/udev/devices/ are not read anymore; systemd-tmpfiles |
| should be used to create dead device nodes as workarounds for broken |
| subsystems. |
| |
| * udev: RUN+="socket:..." and udev_monitor_new_from_socket() is |
| no longer supported. udev_monitor_new_from_netlink() needs to be |
| used to subscribe to events. |
| |
| * udev: when udevd is started by systemd, processes which are left |
| behind by forking them off of udev rules, are unconditionally cleaned |
| up and killed now after the event handling has finished. Services or |
| daemons must be started as systemd services. Services can be |
| pulled-in by udev to get started, but they can no longer be directly |
| forked by udev rules. |
| |
| * udev: the daemon binary is called systemd-udevd now and installed |
| in /usr/lib/systemd/. Standalone builds or non-systemd systems need |
| to adapt to that, create symlink, or rename the binary after building |
| it. |
| |
| * libudev no longer provides these symbols: |
| udev_monitor_from_socket() |
| udev_queue_get_failed_list_entry() |
| udev_get_{dev,sys,run}_path() |
| The versions number was bumped and symbol versioning introduced. |
| |
| * systemd-loginctl and systemd-journalctl have been renamed |
| to loginctl and journalctl to match systemctl. |
| |
| * The config files: /etc/systemd/systemd-logind.conf and |
| /etc/systemd/systemd-journald.conf have been renamed to |
| logind.conf and journald.conf. Package updates should rename |
| the files to the new names on upgrade. |
| |
| * For almost all files the license is now LGPL2.1+, changed |
| from the previous GPL2.0+. Exceptions are some minor stuff |
| of udev (which will be changed to LGPL2.1 eventually, too), |
| and the MIT licensed sd-daemon.[ch] library that is suitable |
| to be used as drop-in files. |
| |
| * systemd and logind now handle system sleep states, in |
| particular suspending and hibernating. |
| |
| * logind now implements a sleep/shutdown/idle inhibiting logic |
| suitable for a variety of uses. Soonishly Lennart will blog |
| about this in more detail. |
| |
| * var-run.mount and var-lock.mount are no longer provided |
| (which prevously bind mounted these directories to their new |
| places). Distributions which have not converted these |
| directories to symlinks should consider stealing these files |
| from git history and add them downstream. |
| |
| * We introduced the Documentation= field for units and added |
| this to all our shipped units. This is useful to make it |
| easier to explore the boot and the purpose of the various |
| units. |
| |
| * All smaller setup units (such as |
| systemd-vconsole-setup.service) now detect properly if they |
| are run in a container and are skipped when |
| appropriate. This guarantees an entirely noise-free boot in |
| Linux container environments such as systemd-nspawn. |
| |
| * A framework for implementing offline system updates is now |
| integrated, for details see: |
| http://freedesktop.org/wiki/Software/systemd/SystemUpdates |
| |
| * A new service type Type=idle is available now which helps us |
| avoiding ugly interleaving of getty output and boot status |
| messages. |
| |
| * There's now a system-wide CapabilityBoundingSet= option to |
| globally reduce the set of capabilities for the |
| system. This is useful to drop CAP_SYS_MKNOD, CAP_SYS_RAWIO, |
| CAP_NET_RAW, CAP_SYS_MODULE, CAP_SYS_TIME, CAP_SYS_PTRACE or |
| even CAP_NET_ADMIN system-wide for secure systems. |
| |
| * There are now system-wide DefaultLimitXXX= options to |
| globally change the defaults of the various resource limits |
| for all units started by PID 1. |
| |
| * Harald Hoyer's systemd test suite has been integrated into |
| systemd which allows easy testing of systemd builds in qemu |
| and nspawn. (This is really awesome! Ask us for details!) |
| |
| * The fstab parser is now implemented as generator, not inside |
| of PID 1 anymore. |
| |
| * systemctl will now warn you if .mount units generated from |
| /etc/fstab are out of date due to changes in fstab that |
| haven't been read by systemd yet. |
| |
| * systemd is now suitable for usage in initrds. Dracut has |
| already been updated to make use of this. With this in place |
| initrds get a slight bit faster but primarily are much |
| easier to introspect and debug since "systemctl status" in |
| the host system can be used to introspect initrd services, |
| and the journal from the initrd is kept around too. |
| |
| * systemd-delta has been added, a tool to explore differences |
| between user/admin configuration and vendor defaults. |
| |
| * PrivateTmp= now affects both /tmp and /var/tmp. |
| |
| * Boot time status messages are now much prettier and feature |
| proper english language. Booting up systemd has never been |
| so sexy. |
| |
| * Read-ahead pack files now include the inode number of all |
| files to pre-cache. When the inode changes the pre-caching |
| is not attempted. This should be nicer to deal with updated |
| packages which might result in changes of read-ahead |
| patterns. |
| |
| * We now temporaritly lower the kernel's read_ahead_kb variable |
| when collecting read-ahead data to ensure the kernel's |
| built-in read-ahead does not add noise to our measurements |
| of necessary blocks to pre-cache. |
| |
| * There's now RequiresMountsFor= to add automatic dependencies |
| for all mounts necessary for a specific file system path. |
| |
| * MountAuto= and SwapAuto= have been removed from |
| system.conf. Mounting file systems at boot has to take place |
| in systemd now. |
| |
| * nspawn now learned a new switch --uuid= to set the machine |
| ID on the command line. |
| |
| * nspawn now learned the -b switch to automatically search |
| for an init system. |
| |
| * vt102 is now the default TERM for serial TTYs, upgraded from |
| vt100. |
| |
| * systemd-logind now works on VT-less systems. |
| |
| * The build tree has been reorganized. The individual |
| components now have directories of their own. |
| |
| * A new condition type ConditionPathIsReadWrite= is now available. |
| |
| * nspawn learned the new -C switch to create cgroups for the |
| container in other hierarchies. |
| |
| * We now have support for hardware watchdogs, configurable in |
| system.conf. |
| |
| * The scheduled shutdown logic now has a public API. |
| |
| * We now mount /tmp as tmpfs by default, but this can be |
| masked and /etc/fstab can override it. |
| |
| * Since udisks doesn't make use of /media anymore we are not |
| mounting a tmpfs on it anymore. |
| |
| * journalctl gained a new --local switch to only interleave |
| locally generated journal files. |
| |
| * We can now load the IMA policy at boot automatically. |
| |
| * The GTK tools have been split off into a systemd-ui. |

| CHANGES WITH 44: |
| |
| * This is mostly a bugfix release |
| |
| * Support optional initialization of the machine ID from the |
| KVM or container configured UUID. |
| |
| * Support immediate reboots with "systemctl reboot -ff" |
| |
| * Show /etc/os-release data in systemd-analyze output |
| |
| * Many bugfixes for the journal, including endianess fixes and |
| ensuring that disk space enforcement works |
| |
| * sd-login.h is C++ comptaible again |
| |
| * Extend the /etc/os-release format on request of the Debian |
| folks |
| |
| * We now refuse non-UTF8 strings used in various configuration |
| and unit files. This is done to ensure we don't pass invalid |
| data over D-Bus or expose it elsewhere. |
| |
| * Register Mimo USB Screens as suitable for automatic seat |
| configuration |
| |
| * Read SELinux client context from journal clients in a race |
| free fashion |
| |
| * Reorder configuration file lookup order. /etc now always |
| overrides /run in order to allow the administrator to always |
| and unconditionally override vendor supplied or |
| automatically generated data. |
| |
| * The various user visible bits of the journal now have man |
| pages. We still lack man pages for the journal API calls |
| however. |
| |
| * We now ship all man pages in HTML format again in the |
| tarball. |

| CHANGES WITH 43: |
| |
| * This is mostly a bugfix release |
| |
| * systems lacking /etc/os-release are no longer supported. |
| |
| * Various functionality updates to libsystemd-login.so |
| |
| * Track class of PAM logins to distuingish greeters from |
| normal user logins. |

| |
| CHANGES WITH 42: |
| |
| * This is an important bugfix release for v41. |
| |
| * Building man pages is now optional which should be useful |
| for those building systemd from git but unwilling to install |
| xsltproc. |
| |
| * Watchdog support for supervising services is now usable. In |
| a future release support for hardware watchdogs |
| (i.e. /dev/watchdog) will be added building on this. |
| |
| * Service start rate limiting is now configurable and can be |
| turned off per service. When a start rate limit is hit a |
| reboot can automatically be triggered. |
| |
| * New CanReboot(), CanPowerOff() bus calls in systemd-logind. |

| |
| CHANGES WITH 41: |
| |
| * The systemd binary is installed /usr/lib/systemd/systemd now; |
| An existing /sbin/init symlink needs to be adapted with the |
| package update. |
| |
| * The code that loads kernel modules has been ported to invoke |
| libkmod directly, instead of modprobe. This means we do not |
| support systems with module-init-tools anymore. |
| |
| * Watchdog support is now already useful, but still not |
| complete. |
| |
| * A new kernel command line option systemd.setenv= is |
| understood to set system wide environment variables |
| dynamically at boot. |
| |
| * We now limit the set of capabilities of systemd-journald. |
| |
| * We now set SIGPIPE to ignore by default, since it only is |
| useful in shell pipelines, and has little use in general |
| code. This can be disabled with IgnoreSIPIPE=no in unit |
| files. |

| CHANGES WITH 40: |
| |
| * This is mostly a bugfix release |
| |
| * We now expose the reason why a service failed in the |
| "Result" D-Bus property. |
| |
| * Rudimentary service watchdog support (will be completed over |
| the next few releases.) |
| |
| * When systemd forks off in order execute some service we will |
| now immediately changes its argv[0] to reflect which process |
| it will execute. This is useful to minimize the time window |
| with a generic argv[0], which makes bootcharts more useful |

| |
| CHANGES WITH 39: |
| |
| * This is mostly a test release, but incorporates many |
| bugfixes. |
| |
| * New systemd-cgtop tool to show control groups by their |
| resource usage. |
| |
| * Linking against libacl for ACLs is optional again. If |
| disabled, support tracking device access for active logins |
| goes becomes unavailable, and so does access to the user |
| journals by the respective users. |
| |
| * If a group "adm" exists, journal files are automatically |
| owned by them, thus allow members of this group full access |
| to the system journal as well as all user journals. |
| |
| * The journal now stores the SELinux context of the logging |
| client for all entries. |
| |
| * Add C++ inclusion guards to all public headers |
| |
| * New output mode "cat" in the journal to print only text |
| messages, without any meta data like date or time. |
| |
| * Include tiny X server wrapper as a temporary stop-gap to |
| teach XOrg udev display enumeration. This is used by display |
| managers such as gdm, and will go away as soon as XOrg |
| learned native udev hotplugging for display devices. |
| |
| * Add new systemd-cat tool for executing arbitrary programs |
| with STDERR/STDOUT connected to the journal. Can also act as |
| BSD logger replacement, and does so by default. |
| |
| * Optionally store all locally generated coredumps in the |
| journal along with meta data. |
| |
| * systemd-tmpfiles learnt four new commands: n, L, c, b, for |
| writing short strings to files (for usage for /sys), and for |
| creating symlinks, character and block device nodes. |
| |
| * New unit file option ControlGroupPersistent= to make cgroups |
| persistent, following the mechanisms outlined in |
| http://www.freedesktop.org/wiki/Software/systemd/PaxControlGroups |
| |
| * Support multiple local RTCs in a sane way |
| |
| * No longer monopolize IO when replaying readahead data on |
| rotating disks, since we might starve non-file-system IO to |
| death, since fanotify() will not see accesses done by blkid, |
| or fsck. |
| |
| * Don't show kernel threads in systemd-cgls anymore, unless |
| requested with new -k switch. |

| |
| CHANGES WITH 38: |
| |
| * This is mostly a test release, but incorporates many |
| bugfixes. |
| |
| * The git repository moved to: |
| git://anongit.freedesktop.org/systemd/systemd |
| ssh://git.freedesktop.org/git/systemd/systemd |
| |
| * First release with the journal |
| http://0pointer.de/blog/projects/the-journal.html |
| |
| * The journal replaces both systemd-kmsg-syslogd and |
| systemd-stdout-bridge. |
| |
| * New sd_pid_get_unit() API call in libsystemd-logind |
| |
| * Many systemadm clean-ups |
| |
| * Introduce remote-fs-pre.target which is ordered before all |
| remote mounts and may be used to start services before all |
| remote mounts. |
| |
| * Added Mageia support |
| |
| * Add bash completion for systemd-loginctl |
| |
| * Actively monitor PID file creation for daemons which exit in |
| the parent process before having finished writing the PID |
| file in the daemon process. Daemons which do this need to be |
| fixed (i.e. PID file creation must have finished before the |
| parent exits), but we now react a bit more gracefully to them. |
| |
| * Add colourful boot output, mimicking the well-known output |
| of existing distributions. |
| |
| * New option PassCredentials= for socket units, for |
| compatibility with a recent kernel ABI breakage. |
| |
| * /etc/rc.local is now hooked in via a generator binary, and |
| thus will no longer act as synchronization point during |
| boot. |
| |
| * systemctl list-unit-files now supports --root=. |
| |
| * systemd-tmpfiles now understands two new commands: z, Z for |
| relabelling files according to the SELinux database. This is |
| useful to apply SELinux labels to specific files in /sys, |
| among other things. |
| |
| * Output of SysV services is now forwarded to both the console |
| and the journal by default, not only just the console. |
| |
| * New man pages for all APIs from libsystemd-login. |
| |
| * The build tree got reorganized and a the build system is a |
| lot more modular allowing embedded setups to specifically |
| select the components of systemd they are interested in. |
| |
| * Support for Linux systems lacking the kernel VT subsystem is |
| restored. |
| |
| * configure's --with-rootdir= got renamed to |
| --with-rootprefix= to follow the naming used by udev and |
| kmod |
| |
| * Unless specified otherwise we'll now install to /usr instead |
| of /usr/local by default. |
| |
| * Processes with '@' in argv[0][0] are now excluded from the |
| final shut-down killing spree, following the logic explained |
| in: |
| http://www.freedesktop.org/wiki/Software/systemd/RootStorageDaemons |
| |
| * All processes remaining in a service cgroup when we enter |
| the START or START_PRE states are now killed with |
| SIGKILL. That means it is no longer possible to spawn |
| background processes from ExecStart= lines (which was never |
| supported anyway, and bad style). |
| |
| * New PropagateReloadTo=/PropagateReloadFrom= options to bind |
| reloading of units together. |
