For "lxc restart", this reproduces reliably (below).
It seems that there may be some race - if "sleep" is set to lower
values, it seems more likely that it will fail.
# while true; do
echo restart time lxc restart containername
sleep 3
done
restart

Am I the only one affected?
Also happens with:
ii lxd
2.0.0~rc2-0ubuntu3~ubuntu14.04.1~ppa1 amd64 Container
hypervisor based on LXC - daemon

"lxc restart containername" mostly just hangs.

Just sits and hangs here.
Is there any quick fix for that?
Other than that - do you have any system which checks basic
functionality before pushing the packages to general public? Seems we
had lots of bugs making lxd unusable lately.
