Yeah I honestly don't mind too much. I actually tried Systemd on Arch not very long ago, as stoat said, many Archers do install it and try it out because it's actually very easy to do and it has backwards compatibility, if that's the right terminology, with the old init scripts and even the rc.conf etc etc.
It will lose that famous BSD style configuration for the most part I suppose, but hey, it will on the other hand be more consistent with most of the other distros.
Hmm so I actually just converted my Arch desktop to pure Systemd (no more rc.conf, inittab etc).
I never thought switching an init system would be so easy, but I guess there is a lot of work behind the scenes, and symlinks etc, done to make the whole process easier. And of course that Arch wiki is great (which is what I followed to make the change).
So I'm not too sure what all the kerfuffle is about
but then I'm not a system admin (except for myself I guess) and probably won't have to debug the thing. But general usage is simple enough.
