An easy way to reproduce this without zfs is:
sudo lxc-create -t ubuntu -n r0
sudo cp /var/lib/lxc/r0/config /tmp
sudo lxc-start -n r0 -f /tmp/config -d
sudo lxc-info -n r0
(it shows up as stopped)
sudo lsof shows that
@/var/lib/lxc_anon/r0/command
is the command socket, not the usual
@/var/lib/lxc/r0/command
You can see it using
sudo lxc-info -P /var/lib/lxc_anon -n r0
Perhaps lxc-instance should be following the config link, making
sure it is in fact $lxcpath/$lxcname/config, and then just doing
lxc-start -n $lxcname?
