I really dont know, why systemd now gains support.
I wasn't kidding about udev. Systemd has taken over distributions through three main vectors:
- Red Hat sponsors the project (the project lead, Lennart Poettering is a Red Hat employee), so they put it in Fedora and RHEL, which caused it to trickle down to all of the RHEL derivatives (CentOS, Oracle, Scientific Linux, etc).
- There was a tremendous political effort to get it pushed into Debian, which caused it to trickle down to the Debian derivatives (significantly, Ubuntu and its myriad derivatives, including Mint).
- Most distributions use udev to load device drivers, so when udev became dependent on systemd, a slew of "other" distributions picked it up.
(For some reason the Red Hat logo isn't showing up next to their root .. it's the one below Slackware, above the various independent lines.)
There are still seventy'ish distributions not adopting systemd, including the most popular Linux distribution in the world (Android). About half of those distributions have either taken positive steps to resist systemd (such as adopting eudev) or publicly announced an intention to remain systemd-free.
I keep some relevant links here for easy reference: http://ciar.org/ttk/...ic/systemd.html
