One of the ideas was that eventually services would expose
*themselves* over d-bus without wrappers, and that would be the
native management framework. I'm not sure how that would fit into

Hm, comparing against a SysVinit bootup *without* rhgb might
be interesting, as it's known that that adds to the startup time.
