If you for whatever reason have a file-system which have become non-responsive and is “hanging” any process which tries to interact with it, regular “systemctl reboot” and “systemctl reboot -force” may fail to actually trigger a reboot, further preventing you from fixing your issue with the non-responsive file-system. In these cases “systemctl reboot —force —force” is useful. Especially on remote machines you cannot physically power-cycle. I don’t remember the exact specifics beyond that, but this has happened to me and I’ve needed this at least once.
