Comment 1 for bug 880030

Thanks for reporting this bug.

This is another side effect stemming from the fact that the kernel doesn't provide a good way to detect poweroff.vs.reboot in containers yet. The workaround is for the container parent to watch the container's /var/run/utmp. As a result of that, we can't let the container mount tmpfs on /var/run, because then the utmp used by the container would be hidden from the parent. As a result of that, /etc/init/mounted-varrun.conf does not run, and that is where /var/run/lock is created.

This should be fixed in lxcguest.conf, which does the other ugly manual recreation of things we want in {/var}/run.
