I have to second this. I am a long-time Linux user, having run Debian since the late 90s and Slackware since 1993 but systemd put me over the edge. Things that worked and were easy to figure out in the previous init system just stopped working under systemd. It is a brutally complicated init that didn't add anything to my experience and pushed me out of Debian and into FreeBSD where things still have sane defaults. I like to get my work done instead of messing around with an init system that refuses to let me do even the most basic things.

Not all new things are great and I think Debian made a mistake not supporting a traditional init system alongside systemd or at least until the kinks could be worked out.
