No, absolutely not, NO, NO, *NO*. *GAH!*

They are not, they are just configured identically.

Also, don’t deviate from the point in question with irrelevent
details. If you must, imaging some kind of dæmon that handles,
oh, say a fuse filesystem.

Looking at their descriptions, I agree. But a new facility
to achieve this is definitely needed.

Not even by calling /usr/sbin/${foo}d? The problem here is that
these are terminated by the initscript, even if that was not used
to start them. I guess systemd can distinguish that but am not sure.
