If I were being practical, I would do just that. But I am on a quest to learn, and in doing so I tend to be a bit eccentric.

Anyways, if I drag the whole rc.d structure in, wouldn't I have to bring along all the required binaries as well? 

My goal for this whole excercise is to learn about the components of NetBSD and put together a document that shows you how to make an absolute minimal NetBSD. This is mainly targeted at embedded developers who would want a full featured OS without any more code than is absolutely needed.

Anyways, it looks like the 'ttyflags -a' wasn't enough. I see there is a /etc/rc.d/wscons file that runs wsconscfg. However it is a bit hard to follow as to what it is doing because many of the parameters look to be passed in on the command line. All I want to do is initialize my console (on an i386). Looking through the man page for wsconscfg was little help either, since I do not understand the whole wscons system (ungh! more reading!).

I'm going to try adding a 'wsconscfg -t 80x25 -e vt100 0' to my startup script to see if that helps.
