Sure, and I'm the first to agree, but that's beside the point. I mean,
at least part of my current OS keeps running just fine if I kill the
system bus daemon.

Ah, OK, I see - very nice, systemd FTW. So, yeah, if we can guarantee
that no unprivileged process can grab the socket in the meantime (if
even for a split-second) then I guess that my objection doesn't
matter.

We still have the other problems to deal with though.
