Today I just learned that systemctl --force --force reboot is a command. We had a computer we remotely connected to which got permission errors and bus errors when we tried to reboot it normally. For some reason the mentioned command did actually manage to shutdown the computer bit did not manage to reboot it correctly.
I wonder what the double --force flag actually accomplishes and what possibly could hinder a regular reboot in this scenario.
I would use the man pages but my working laptop uses Windows and since the system died i dont have any way to check them until I get home.
Thank you a lot for the answer though, that does explain a lot!
