| <title>Description</title> |
| |
| <para><command>systemd-firstboot</command> initializes the most |
| basic system settings interactively on the first boot, or |
| optionally non-interactively when a system image is created. |
| The service is started if <varname>ConditionFirstBoot=yes</varname> |
| is satisfied. This essentially means that <filename>/etc/</filename> |
| is empty, see |
| <citerefentry><refentrytitle>systemd.unit</refentrytitle><manvolnum>5</manvolnum></citerefentry> |
| for details.</para> |
| |
| <para>The following settings may be set up:</para> |
| |
| <itemizedlist> |
| <listitem><para>The system locale, more specifically the two |
| locale variables <varname>LANG=</varname> and |
| <varname>LC_MESSAGES</varname></para></listitem> |
| |
| <listitem><para>The system keyboard map</para></listitem> |
| |
| <listitem><para>The system time zone</para></listitem> |
| |
| <listitem><para>The system hostname</para></listitem> |
| |
| <listitem><para>The machine ID of the system</para></listitem> |
| |
| <listitem><para>The root user's password</para></listitem> |
| </itemizedlist> |
| |
| <para>Each of the fields may either be queried interactively by |
| users, set non-interactively on the tool's command line, or be |
| copied from a host system that is used to set up the system |
| image.</para> |
| |
| <para>If a setting is already initialized, it will not be |
| overwritten and the user will not be prompted for the |
| setting.</para> |
| |
| <para>Note that this tool operates directly on the file system and |
| does not involve any running system services, unlike |
| <citerefentry project='man-pages'><refentrytitle>localectl</refentrytitle><manvolnum>1</manvolnum></citerefentry>, |
| <citerefentry><refentrytitle>timedatectl</refentrytitle><manvolnum>1</manvolnum></citerefentry> |
| or |
| <citerefentry><refentrytitle>hostnamectl</refentrytitle><manvolnum>1</manvolnum></citerefentry>. |
| This allows <command>systemd-firstboot</command> to operate on |
| mounted but not booted disk images and in early boot. It is not |
| recommended to use <command>systemd-firstboot</command> on the |
| running system while it is up.</para> |

| <variablelist> |

| <term><option>--root=<replaceable>root</replaceable></option></term> |
| <listitem><para>Takes a directory path as an argument. All |

| <varlistentry> |
| <term><option>--image=<replaceable>path</replaceable></option></term> |
| <listitem><para>Takes a path to a disk image file or block device node. If specified all operations |
| are applied to file system in the indicated disk image. This is similar to <option>--root=</option> |
| but operates on file systems stored in disk images or block devices. The disk image should either |
| contain just a file system or a set of file systems within a GPT partition table, following the |
| <ulink url="https://systemd.io/DISCOVERABLE_PARTITIONS">Discoverable Partitions |
