From 57f949a7ab34812d8384bf41c05c3b25bdade92b Mon Sep 17 00:00:00 2001

Subject: [PATCH] plugins/services: add basic sysvinit implementation
This allows operation on systems that don't have the "service" command.
The PID finding is a little hacky but mostly works. Note that this uses
psutil to detect whether the service is really running rather than just
assuming that it is if the pid file exists.
Note: you need to remove s_upstart.py before this will work.
