Yeah, I agree systemd makes things easier for sysadmins, and with every components of it to be fair. It's quite a huge project at this point, does way more things than a mere init system, I guess that's the argument of it being not so Unix-like. It's made specifically for Linux so it probably doesn't work on BSDs, though I have no idea honestly. Wayland was suppose to be the same and it works on some BSDs now apparently. Anyway, if I imagine system administration on bigscale, I think I would go with systemd as well.
