Package: systemd
Version: 44-11+deb7u4
Severity: important
Tags: upstream patch
Hello,
I am running a Debian Wheezy system in a OpenVZ container and found that
systemd just shuts down when "systemctl reboot" is run. The container then
has to be started again via the control panel. A OpenVZ developer had posted
a patch to the systemd-devel mailinglist in August 2012 but the systemd
version in wheezy iss too old to include the patch. This is the post:
http://lists.freedesktop.org/archives/systemd-devel/2012-August/006379.html
I have applied the patch to the sources of the systemd debian package and
attached the diff to this report. The problem seems to be that OpenVZ needs
the reboot systemcall to be issued in the container to reboot. Version 44-11
just exits inside of a container.
It would be great if the package in wheezy could be fixed, as the systemd
version from wheezy-backports (204) is not compatible with the OpenVZ kernel
(systemd 204 needs a kernel >= 2.6.39 and OVZ only has kernels up to 2.6.32).
It is unfortunately not possible to use SysVInit in OVZ, because this hangs
when init starts up.
Best wishes,
Daniel Edwards

I decided to not apply this unofficial patch for wheezy, and as jessie
as I've been told, has a working vzctl, I'm going to close this bug report.
