Not at all. I'm possibly suggesting actually using udev features, but

Somehow I get the feeling that I've asked this before, in which case I'd
be repeating myself, which is very rude of you ... but ... *which* events !?
If it's only device hotplugging / uevents we already have a handler for
that that can execute arbitrary code (udev/mdev), if not then someone
should at some point in time enlighten me what "event based" means to
them so I can finally see why people are disagreeing there. 'cause right
now it looks like violent agreement to me, which makes little sense

Sense ... if we had some more of that this discussion wouldn't have
started at all
