To address several issues which continue to arise ....

1. We have presented two papers comparing "Bell UNIX" and "Berkeley UNIX":

	"UNIX System III and 4.1BSD, A Practical Comparison"
	(Winter 1983 USENIX Conference, San Diego)

	"UNIX System V and 4.1C BSD"
	(Summer 1983 USENIX Conference, Toronto)

Contrary to popular rumor, we have presented nothing comparing:

	4.1 BSD and 4.2 BSD
	System V and 4.1 BSD
	System V and 4.2 BSD
	System V Release 2 and anything

The Toronto paper obliquely referenced the state of 4.2 BSD at that
time. It does not necessarily correspond in all details to the actual
system which was distributed some time later.

2. The paper "UNIX System V and 4.1C BSD" is marked

	(c) Copyright 1983 by the Regents of the University of Texas.

solely in order to prevent its sale by anyone other than the USENIX
Association. The paper may be distributed free of cost in any quantity,
by any means and by any entity so long as the whole paper, in one of
the forms originally distributed by us, including the copyright notice,
is distributed. Properly attributed quotations in reviews and other
papers are of course also permitted.

The paper is available in the Proceedings of the Summer 1983 USENIX
Conference, by anonymous FTP as compare.doc from ut-sally.ARPA, and by 
UUCP from ut-sally.UUCP and several other UUCP sites; it was also posted 
to net.sources on USENET.

	To use anonymous ftp, connect with ftp to ut-sally,
	login as anonymous, password guest, and get or retrieve
	compare.doc.  The authors are no longer associated with
	utexas-11 (which is now known as ut-ngp, anyway), but
	principally with ut-sally (which happens to be the
	VAX-11/780 referred to in the paper).

We would rather not have to mail out individual copies to everyone in
the world. Get it from your neighbor if you can.  If there is still
demand we might post to net.sources again.

3. We feel that questions of comparative performance were adequately
treated at the Salt Lake City USENIX Conference, particularly in: 

	"UNIX System V and 4BSD Performance"
	Jeffrey P. Lankford, AT&T Bell Laboratories

	"Measuring and Improving the Performance of 4.2BSD"
	Sam Leffler (Lucasfilm, Ltd),
	Mike Karels, and M. Kirk McKusick (U.C. Berkeley)

It is therefore not our intention at this time to distribute the
results of any such studies which we ourselves may have conducted.
