Or you could use "systemctl -f shutdown" to tell systemd to stop
waiting on all the furshlugginer services it desperately wants
to shutdown "cleanly" (which won't make a particle of difference
unless you are running something like a database server that
really does need to shutdown cleanly). With -f all it does
is sync the disks and go bye-bye.
