start on starting libvirt-bin

# when cgconfig has started, that means its pre-start script must have
# stopped, meaning /usr/sbin/create_default_cgroups is finished
# reclassifying tasks.  Libvirt is safe to start once we know it won't
# get reclassified.
stop on started cgconfig

	# As soon as cgconfig starts, our 'stop on' will trigger.
	# If cgconfig takes more than 120 seconds to start, then go
	# ahead and start libvirt-bin.  What matters most is to have
	# libvirt's cgroup not change.  After 120s we can be pretty
	# sure it just won't.
