First off: I feel I must apologize to Ricky Palmer (and to the
Ultrix group in general I suppose) for the uncalled-for virulence of my
posting. He really didn't deserve it (well, maybe *he* did, but his
posting certainly didn't). I realized this about a day later, after I'd
cooled down and the article had made its way out onto the net. And I
didn't know how to cancel an article (still don't, anyone out there want
to enlighten me?)

If you did a fair amount of work on it then it is not 4.2, it is
*modified* 4.2 (as you yourself say a sentence or two later).

My main complaint (read my original). We *do* require other kernel
hacks, notably in trap.c (kernel_user traps, so errors in kernel mode
can be made to signal a user process instead of panic()ing) and locore.s
(so we could grow the cmap struct for memory mapping--no sysV flames
please!).

At least you tried.

Exactly. I forget sometimes there is a real world out there.

Well, we have some outstanding VMS SPRs which are a year or two old
(yes we do run VMS on one machine; a historical artifact).... Maybe the
rest of the company needs to look at their measurements? (:-)

I didn't say this was your attitude, or even the prevailing
attitude at DEC; that was what I saw at the time in Palmer's posting. I
think maybe I do have an idea of how Ultrix would or would not [the
latter] fit our situation; we had a uVAXII with Ultrix on it here for
evaluation, so I have some sort of idea what Ultrix is like.

Point taken, though I feel it isn't quite that extreme; Ultrix does
make some sort of claim to being 4.2bsd [/bin/ed doesn't pretend to be a
full screen editor]. I will try to remember to cool down before posting
in the future.
