     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?)

> Ultrix *is* 4.2 with a fair amount of work by DEC [ ... ]

     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.
