More to the point, why would an initscript do that, since it's *already*
running as root?

Though I'm sufficiently out of the loop regarding the architecture that
I don't see how "su" can have such complexities -- As far as I know, its
purpose is to create a subprocess whose UID is different from the UID of
this process; in no way is it intended to be "a separate login".  Why
would shutting down "logind" suddenly cause one of my subprocesses to
vanish?
