The /dev/console device is a "redirector" in that it can not do
anything without having a "real" device to point at.  The redirection
stuff is implemented in the (generic) sys/dev/cons.c but its pointer
to the real device is set by sun3-specific code (sun3/dev/zs.c) based
on the EEPROM settings.

Right.  If you never run a getty on /dev/console, then you will
never get "dualing gettys" due to a /dev/console alias.

Hey, that would be great!  (I loathe doing documentation...)
