Comment 27 for bug 350936

but i am still hanging on the upstart integration when using pre-stop in libvirt-bin. while the condition regarding the runlevel by tomcrus works great, it seems we are not able to simply delay the shutdown process with a simple sleep. in my case i only managed to get the pre-stop killed or make the reboot hang forever. i also tried "exec sleep". there is also some stuff in /etc/init.d/sendsigs that might be of interest.

for anyone who like to do the puzzle just make the timeout work in pre-stop and we should have the solution by placing the core script into it.
