At a low level, how does "shutdown now" work? It's part of the upstart package and not anything distribution specific, so it appears as though it does something related to emitting upstart events to me, but I'm not clear on the internals of upstart to know how to signal it to do something at a low level. I do have a case with Red Hat open on this as well, but at this point I'm trying all of my options to figure out a way to do this :) </blockquote></div>
