Re: SMF?
I have a hard time understanding why all the other Linux distros joined hands with Redhat and implemented that thing, systemd
Several reasons:
A lot of other distros use Redhat (or Fedora) as their base and then customise it.
A lot of other distros include things dependant on systemd (Gnome being the one with biggest dependencies - you can just about to get it to run without systemd but it's a pain and every update will break your fixes).
Redhat has a lot of clout.
