[lxc-users] lxc-autostart, systemd and cgroups

[Fajar A. Nugraha]

Yep. I don't know when it was fixed, but my test system works fine. This is
after a reboot:

root at debian:~# lxc-ls -f
NAME  STATE    IPV4        IPV6  GROUPS  AUTOSTART
--------------------------------------------------
c1    RUNNING  10.0.3.194  -     -       YES

root at debian:~# lxc-attach -n c1 -- cat /proc/self/cgroup
8:cpuset:/lxc/c1
7:cpu,cpuacct:/lxc/c1
6:devices:/lxc/c1
5:net_cls,net_prio:/lxc/c1
4:freezer:/lxc/c1
3:perf_event:/lxc/c1
2:blkio:/lxc/c1
1:name=systemd:/lxc/c1

I also updated manually to a newer version of systemd though, but it
shouldn't matter in this case
root at debian:~# dpkg -l systemd lxc lxcfs
