Helpful to know.

Thanks for trying.

See my answer to #428.

Yes, it might come to that. However, I would like to exhaust other possibilities
first.

A few other ideas to try: obviously the lxc container is looking for the host
/sys/fs/cgroup/systemd which doesn't exist. Does creating it manually help?
Does installing cgmanager help (I am not sure if that will create and manage
/sys/fs/cgroup/systemd)?
