Comment 2 for bug 1459755

I suspect the serial port name might differ (e.g. ttyS0 and ttyS1) and that people might want to disable that if they actually need the serial port for something else.

It kind of feel like a deployment option to me: headless servers where you want to use an existing serial port, but some platforms wont have it; perhaps there's a smart way to detect it though, like "press space now to enable serial console" during grub startup?
