[lxc-devel] disable container start if lxcfs is not running

[Dietmar Maurer]

Hi all,

for some unknown reason lxcfs crashed (will try to debug). But after 
that, I am still able to start containers, which now have 
wrong /proc and cgroup mounts.

I wonder if it would be safer to disable container start if 
lxcfs is not running, something like:
