The whole idea of a "system console" is somewhat antiquated. Nobody
really needs one for message logging and init should really re-direct
I/O to a file for startup logging. Sure it might be nice to have TTY
interrupts pointed at /etc/rc processes during boot, but that's really
only for debugging, right? Once you get the bugs out of your boot
scripts then you don't need a terminal connected to /etc/rc again until
the next time you make some configuration change. About all that's left
is true single-user mode where init needs to know which TTY to start a
shell on. Note also that there needn't be any link between a kernel
console and whatever TTY device init uses.
So, telling people that they really need a console on a headless server
isn't really very helpful, because they don't _really_.
