It is actually very easy. Just one keyboard, and just one monitor is "system console". All others are just normal terminals.
There's already same problem with serial console / vt problem. There's solution saying "user selects using command line what _real_ console is". No new problem here.
[And yes, serial console can do both sysrq and printing kernel messages. No new problems here.] Pavel -- I'm pavel@ucw.cz. "In my country we have almost anarchy and I don't care."
