Title:
pm-hibernate dies if parent dies upon wake
Status in “pm-utils” package in Ubuntu:
Incomplete
Bug description:
By-the-book behaviour of pm-hibernate/-suspend may cause issues.
The issue: when waking up, the hooks that were run before sleeping /
suspending are executed in reverse order as explained on the man page.
When such a hook (accidently) kills the parent process which triggered
pm-hibernate/-suspend in the first place, this child process in the
shape of pm-action is killed alongside the parent (regardless of sudo
invocation or not).
A possible solution would be to daemonize the script after wakeup by
the kernel so that init inherits it and can forget about it after pm-
action exits.
First observed on a stock Precise / Oneiric 64 bit installation.
Steps to reproduce:
1) Write a hook that calls initctl to restart a service as non-root
2) Have this service execute pm-hibernate.
3) Watch pm-action terminate in pm-functions when parent process dies due to
service restart in hook invocation.
