[pkg-lxc-devel] Bug#850212: lxc: lxc init script should depend on cgroupfs-mount

[Benda Xu]

Package: lxc
Version: 1:2.0.6-1~bpo8+1
Severity: important

Dear Maintainer,

lxc requires cgroupfs to be properly mounted.  This task is either done by
cgroupfs-mount init script or systemd.  The former does nothing if started
by systemd:

  # Test for systemd and bail (we have to test before sourcing init-functions, or systemd hijacks us)
  # We bail because systemd already mounts cgroups sanely, so we just silently pretend we were successful in mounting them here
  if [ -d /run/systemd/system ]; then
      exit 0
  fi

Therefore adding cgroupfs-mount to the service dependency of lxc fix startup
issue on non-systemd systems.
