Re: Shutdown - 25 Years Later

Just having a look at what your above situation might be about:

    lrwxrwxrwx 1 root root 12 Apr 13 17:40 /dev/initctl -> /run/initctl
 
So this is a named pipe used for communicating with init. Why would it
be deleted? Because there is no way to stop the init process without
bringing down your system (pid 1 is special that way). Perhaps
something else deleted the pipe. If it was just the symlink that was
removed, it should have been possible to put it back.

Going back over the thread, I did figure out and post that the root
issue was systemd failing to recover after a hibernate event. So the
pipe was probably still there, but systemd was out to lunch.

Someone suggeted "magic sysrq keys" as an alternative way to shutdown
the system, but what a mess.
