vzevent-stop: workaround for F17 that doesn't call reboot()
The problem is systemd from Fedora 17 doesn't invoke reboot()
syscall at all, so kernel doesn't know if CT is rebooted and send us
stop event instead of reboot event.
The workaround has two parts
1 vzdummy-systemd-f17 package installed inside an F17-based container
have /usr/lib/systemd/system/vzreboot.service file (and a symlink
to it from /lib/systemd/system/reboot.target.wants/) which does this:
[Unit]
Description=Tell that Container is rebooted
ConditionPathExists=/proc/vz
ConditionPathExists=!/proc/bc
Before=reboot.service
DefaultDependencies=no
[Service]
Type=forking
ExecStart=/bin/touch /reboot
TimeoutSec=0
RemainAfterExit=no
2 This patch, that checks existence of $VE_ROOT/reboot file and
execs vzctl start.
So, container will be restarted even if it doesn't do reboot()
We do sourcing vz.conf and $veid.conf in a subshell to not clog
the current shell with lots of environment variables.
