Yes, I am one of those Linux jockeys who loathe systemd. Why? In a nutshell, I have had more unscheduled downtime directly attributable to systemd than all other downtime combined over the past fifteen years.
I have one whitebox router I built that loses its iptables settings on reboot, leaving this web site and a few others unreachable until I sign on and manually reset the iptables rules. Naturally, I blamed some systemd weirdness. As it turns out, it was due to a small init script I had written to work around a bug systemd had when it was first released. So, though the mistake was actually mine, it wouldn’t have happened if there hadn’t been an opaque bug in systemd.
I just hope the Devuan gets the ongoing love it deserves.
