The machine always has to have a console, no matter what.  This is true of
most UNIX systems, and probably of a lot of non-UNIX "general purpose"
OSes out there as well.

Unfortunately, the PROM monitor doesn't know "/dev/null" from a hole in
the ground, so even if you could somehow set up the EEPROM so that UNIX
thought it was to use "/dev/null" as the console (you can't - according to
<mon/eeprom.h>, the only alternatives are tty port A or B, the B&W
monitor, the color monitor, or the P4 monitor), you couldn't get the PROM
monitor to do so.
