Just re-read through this whole bug.

It looks like what broke your setup is actually a bugfix in LXC wrt
config inheritance.

Your config contains:
 - lxc.mount.auto =
 - lxc.mount.auto = cgroup:mixed

This instructs LXC (and that wasn't implemented right at first) to wipe all of lxc.mount.auto, and then set cgroup:mixed.
Doing so unsets the default which did contain sys:mixed, causing the breakage you had.

So the issue is that LXC actually does what you ask it to do now :)

  It seems a fairly recent update to LXC has caused this.  This is a
