Public bug reported:
Starting in Ubuntu 15.04, while using systemd as init, running
containers are being stopped when an lxc package upgrade occurs. In
older Ubuntu releases, running containers are still up after lxc package
upgrades.
Serge reports that a simple `apt-get install --reinstall lxc` will
reproduce this bug.
Here's another reproducer where I did a no change rebuild of lxc
1.1.2-0ubuntu3 as 1.1.2-0ubuntu4~nochange1:
tyhicks@sec-vivid-amd64:~$ sudo lxc-ls -f

tyhicks@sec-vivid-amd64:~$ sudo lxc-attach -n somename -- hostname
