OK so back to a specific example on Fedora 24 with a restart/shutdown delay. User gdm owns session-c1.scope, and for some reason I can't figure out, it won't quit on its own. So it enters a failed state 1m30s after I ask for a restart/shutdown. [1] I edited /etc/systemd/logind.conf uncommented KillUserProcesses=yes and rebooted. And at the next reboot, the problem still happens. While the user session itself is gone, and lsof /home no long shows user chris processes holding things up, user gdm still is causing the hang. Since some other user process is the cause of the delay, and apparently isn't subject to killuserprocesses, at least in this instance it's not fixing (or papering over) this particular example of a restart/shutdown delay. I don't know that this is a bug, but I went ahead and filed it because it seems like killuserprocesses=yes should apply to user gdm, because that user isn't an excepted user (unless it's functionally the same as root, in which case the default #KillExcludeUsers=root is probably why, and now we're just back where we started where there are wayward processes that are causing restart hangs and are difficult to identify.
