Title:
  cgroup-lite should be added as an explicit dependency

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  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 /sys/fs/cgroup/blkio/grp_1
  lxc-start: Device or resource busy - cgroup_rmdir: failed to delete /sys/fs/cgroup/cpu/sys_daemon
  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.
