I fully agree with this... I tried to use a DECstation's console
briefly. I've also found NetBSD 0.9's default console to be lacking
somewhat... resize(1), for example, throws it for a loop. I think
that a good VT102 emulator is dandy. It's highly useful with just
about any system you login to.

How much? Part of the problem here might be that the console has been
dramatically improved already. Nobody but Brad and Lawrence have seen
it, and the debate should probably be postponed until we do.

That depends on how much rope the drivers give you. X has to do pointer
tracking and bitmapped graphics. It does so by negotiating with the
various drivers. Any other user-land program should theoretically be
able to do this. If additional hooks are put into the console code to
support reduction of the scrolling region of the screen, a user-level
program could, indeed make a menu bar on the top of the screen.

I don't think that this, or the PMAX, or probably the suns have a built-in
80x24 (or any other) character generator. In fact,

I think that user-level programs are the best way to do it. The kernel
provides the "how," the user-level programs provide the action.

I don't see it as that. I see it as a "Let's kick the bloated kernels."
We have some NCR machines at work running SVR4-MP. They have 16MB of
RAM. After booting, there are about 5 free. Yes, I've looked at all
the tunable parameters and made sure that all the extraneous drivers are
removed from the kernel. It's still taking 11MB. I have no clue why,
but NCR says that the minimum RAM requirements are 16MB. ARGH!!!!!!!

The adequate, valid reasoning that I have to offer is that there are
other things that *need* to be done by the end of this week.
