That did not fix reboot yet. I filed bug 1514690 as it's a different root cause apparenlty. @Serge: there's nothing that should "stick around", it's a reboot after all and everything including pid 1 gets restarted. It just seems that the second boot can't create the init.scope cgroup as the

Hi Martin, thanks for that info. During a reboot, lxc deletes the container's cgroup, then recreates it. Is systemd expecting the cgroup it previously created to stick around? -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to lxc in

FTR, I tried the above lxc patch locally, and it does not resolve the reboot bug in a xenial container. I. e. "sudo reboot" in such a container still fails during very early boot due to a cgroup setup error. -- You received this bug notification because you are a member of Ubuntu Server Team,
