[Service]
ExecStartPre=/bin/systemctl start serial-console-conf@%i.service
Clean up systemd jobs. The main visible effect of this is that if console-conf crashes or is killed it restarts instantly rather than 90 seconds later. It also removes the flicker where a getty gets started and then instantly killed during startup. 2016-09-01 10:33:00 +00:00			`[Service]`
