14 It is possible to specify multiple devices for console output. You can
16 use for console output.
20 console=device,options
22 device: tty0 for the foreground virtual console
23 ttyX for any other virtual console
35 You can specify multiple console= options on the kernel command line.
39 the last device will be used when you open ``/dev/console``.
