systemd has tty arbitration logic. Maybe it is failing in this
case for some reason... rescue.service has StandardInput=tty-force,
which means that when it is started, previous owners of the tty
should be killed. And the other way around, getty@ should wait
until the previous owner goes away on its own. Explicit conflicts
should be unnecessary.
