Thanks, I usually know what it is tho. Most often it’s VMs I was using for testing stuff, which I forgot to shutdown. It takes a while for them to cleanly shutdown, which is what the wait is for. I have a shortcut on my desktop to a script that checks for any running VMs still and shuts them down. But I forget to click it sometimes and then I have to wait. No big deal, except I like to switch off the power bar that powers the computer and everything attached to it. An old habit from when such a thing mattered, these days standby power is probably nothing to worry about. But still I wait patiently for the computer to shut down till I switch off the power strip.
If your script somehow shuts them down faster than plain old SIGTERM, putting it under /usr/lib/systemd/system-shutdown/ might be a good idea. Check man 8 systemd-shutdown for more info on that.
I entrust you with this horror, go figure out what to blame.
