That we do that in PID 1 is because we have to allow communication
with PID 1 even before dbus is around. That's the only reason. The
code for it I *really* dislike and am looking forward to removing as
soon as we can hard-depend on kdbus.

With code like that you just write your own little (crappy!)
dbus-daemon inside each daemon, that's a bad idea.

No. Sorry. That PID 1 does this is a *bad* thing to remove as soon as
we can, not a good thing to copy to any other daemon.
