That's exactly what I meant. There should be a target for units that
"need to be waited" and "no need to be waited" respectively. One can
argue which one should a sound service fall into with whatever point,
but that's out of the scope of the issue I am talking about here.

I just thought systemd has implemented this at its very beginning,
seems like I was wrong. At I least I got my answer though. Thanks,
