From: Randolph Sapp <[email protected]> Adding serial consoles to this variable makes systemd attempt to start a Getty instance on them. Getty has no retry limit and no retry timout. I'm sure you can guess where this is going.
This fixes the endless start / stop Getty on ttyS0/ttyS3 messages that will flood the log until it's full. In the case of Jailhouse demos, the getty systemd service should be invoked upon demo start and stopped upon end of the demo. It should not be listed as a system serial interface since it will not be present during normal device operation. Before anyone asks, SERIAL_CONSOLES_CHECK only works on the sysVinit script so it's not worth discussing as a solution here.
