edit2: This question keep getting closed with links which point to completely irrelevant posts so giving up on it.
edit: I'm asking how to disable/kill the Stop Job, not change the time to SIGKILL (which apparently isn't working either since 90s is the default).
I have a few Debian 10 systems (Proxmox) which take anywhere from 5 minutes to forever to reboot.
Sometimes I need to drive into the DC and physically hit the power button. The keyboard is always unresponsive at this point. I don't know if USB is already disabled in the reboot process or what. The holdup is always Systemd with "A stop job is running". Today it appears to be the swap partition.
Any way to put a kill-switch on the stop jobs? I don't care if swap gets hosed due to a dirty unmount - At this point, I'd rather just fsck -Cf after every reboot and mount swap by hand.
