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 always try to consult the man pages for these kind of questions (you can search by typing ‘/’ in the man page). Here’s what the systemctl manual has to say in the specifications for the --force option:

    Note that when --force is specified twice the selected operation is executed by systemctl itself, and the system manager is not contacted. This means the command should succeed even when the system manager has crashed.

      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!

        You just really force it.

        It’s like with -v in various applications. -v means “verbose”, and -vv means “really verbose”, and -vvv means “an ungodly amount of data printed to the terminal, so much that it might crash”.
