Exactly... what's needed is a simple list of what services are known
to shutdown cleanly if they're just whacked by init/killall (as opposed
to something like a database, or some other app that needs to save state.)

Then, we don't even need to run the shutdown scripts for those apps.

(Obviously, this is a whitelist scenario; any service that doesn't
claim this property needs to be shut down in the 'normal' way.)
