The Problem, as I understand it from my paleolithic point of view, is
that there is, i.e., no /dev/com0, no /dev/puc0, etc. to determine
precisely where you're attaching.
I can imagine that it would be quite frustrating to have to divine which
port you were on (though plugging in and typing 'tty' once you got to
single-user mode wouldn't be too difficult :/ ).
...or is the problem plugging into the "wrong" serial port in the first
Can we even force a console at a particular place?
As the kernel prints
root on wd0a dumps on wd0b
Could it not also note
console on <wherever>
...or would that even be useful?
I'm just tossing darks, here -- taking shots at straws...
