Otherwise you'll get an error
sudo lxc-start -n mycontainer
lxc: call to cgmanager_move_pid_abs_sync(blkio) failed: invalid request
lxc-start: Could not find writable mount point for cgroup hierarchy 11 while
trying to create cgroup.
lxc-start: Device or resource busy - cgroup_rmdir: failed to delete

lxc-start: Device or resource busy - cgroup_rmdir: failed to delete
/sys/fs/cgroup/cpuset/
lxc-start: failed creating cgroups
lxc-start: failed to spawn 'mycontainer'
Or at least let the "lxc-start" check of the presence of the "cgroup-
lite" and show a meaningful error message.
Ubuntu vanilla installs the "cgroup-lite" automatically, so it doesn't
affect fresh installs.
