Indeed, that would interest me as well.

Either approach sounds fine to me. Changing dbus-uuidgen seems a bit
more universal as then distros don't need to all do the same postinst
change and /etc/machine-id validity check (which dbus-uuidgen already
does), but either way it should be simple enough.

Thanks!
