Just to spell it out for perhaps newer users to *nix if PID 1 (ie now basically systemd in Linux land) goes down the kernel is required to panic (BSOD in Windows terminology). Therefore systemd is so much more than an init replacement its proponents (basically Red Hat) claim. Its stability now on the majority of Linux distros is as important as the stability of the Linux kernel itself. Therefore, Red Hat shoving shit into PID 1 has a lot more to do with Red Hat business and political reasons than technical ones. Sadly the one thing Red Hat has shown at least me is they basically drive a whole lot of the development in Linux land these days so they can get away with this.
