#action_restart ⇒ Object

True restart in Upstart preserves the original config data, we want the more obvious behavior like everything else in the world that restart would re-read the updated config file. Use stop+start to get this behavior. http://manpages.ubuntu.com/manpages/raring/man8/initctl.8.html
