[snip] Could systemd do a better job saying what it was waiting on?  Yes.  Is it so horribly broken it doesn’t know how to exit? No.

This kind of blanket dismissal of user feedback and refusal to believe *even the possibility* that systemd could be broken in obvious ways contributes to the sense from the community that negative feedback about systemd has been and will be ignored.

Had the response been "What kind of system was it? What test cases did you do? Which time frames?" then at least it would come across as a constructive attempt to solve the problem. But a blanket dismissal of the possibility that systemd could fail to exit cleanly as opposed to admitting that maybe they were bit by any of the previous bugs where systemd would crash on exit [1, 2, 3, 4] reinforces the sense of "systemd advocates don't listen to user feedback".

Just as much as frustrating as people who say “systemd is evil” and because it has bugs it should be tossed out entirely. I wasn’t trying to be dismissive, I just didn’t realize we were debugging someone’s genuine problem.

In general, the way I suggest debugging these kinds of hangs at shutdown/reboot are to run:




journalctl --boot=-1 --reverse
