That's a good hypothesis, especially given the info I presented, but I do
have -some- things under /usr, and if I manually rerun sh -x /etc/rc in
multiuser, I get an error about /usr already being mounted.

I'm thinking /usr is /dev/rp3, because my /etc/rc looks like:
# cat /etc/rc
PATH=/bin:/usr/bin
echo "Restricted rights: Use, duplication, or disclosure
is subject to restrictions stated in your contract with
Western Electric Company, Inc." >/dev/console
rm /etc/mtab
cat /dev/null >/etc/utmp
/etc/mount /dev/rp3 /usr
rm -f /usr/spool/lpd/lock
: /etc/accton /usr/adm/acct
rm -f /usr/tmp/*
rm -f /tmp/*
/etc/update
date >/dev/console
/etc/cron

This does seem to at least try to mount /usr for me - hitting ctrl-d at the
initial singleuser #, that is.
Interestingly though, it seems that the number of directories in /usr is the
same on first boot into single user, as after /etc/rc has run as part of
entering multiuser, so perhaps my root filesystem has things in /usr that
would normally be obscured by a /usr mount. Also, /etc/mtab seems untouched
(in fact, it's nonexistent) after entering multiuser, and the output of
/etc/mount continues to be nothing.
touch /t does create a file named t in the root directory, so it's not
something about the root filesystem being readonly.
I'm puzzled. And yet, I'm enjoying it. :)
Any suggestions?

What type of licensing agreements (maybe informal) were used for the
early INGRES tape distributions? I am trying to see if they were an
example for BSD or how compared with early BSD.
The BSD-style licenses were not introduced until 1987 and later
(starting in but not completed in 4.3BSD-Tahoe). But various earlier BSD
(distribution) components did have open source licenses long before that
-- such as Eric Allman's trek (circa 1977) in 1BSD and MIT's X
components (1985) shipped with 4.3BSD.
The COPYRIGHT for INGRES 6.3/-1 (February 1, 1981) source shipped with
2.79BSD (Febuary 1981) indicated it was not open source: "... may not be
reproduced or disclosed without the prior written permission of the
owner."
My BSD history book in progress has at least 15+ pages of examples and
commentary and interview quotes about the history of proprietary and
open source licensing in early BSDs. I also plan to research the
history of licensing for W and early X.
Hi Warren.
Here's your answer. :-)

All, apologies for these seemingly random questions. How many children does
Ken Thompson have? I want to use the phrase that Unix was "Ken's other child",
but it would be inaccurate if he had several real children.
Thanks,
Warren
All, thanks for the help with that image of Ken and Dennis at the 11/20
console. Now I'm after a reference/citation to a great quote attributed to
Henry Spencer:
Those who don't understand Unix are condemned to reinvent it, poorly.
Any ideas if/when Henry said this and where: date, first time it appeared
in print etc.
While we are at it, are there any other good Unix quotes that spring to mind?
Thanks,
Warren
I went to Dennis' home page this morning to find something, and it seems
to be gone. The URL I'm using is http://cm.bell-labs.com/cm/cs/who/dmr/
Does anybody know if it's moved or, if not, who to contact to fix it?
I'm actually after the hi-res version of the photo with dmr and ken
at the PDP-11/20 console. I think I have a copy cached away. If not, does
anybody else have a copy?
Cheers,
Warren

Looks like there has been substantial reorganization of
the company's web pages, doubtless to reflect reorganization
of the company itself.
I dug around to see where personal web pages seem to be now,
and tried some obvious guesses, and still couldn't find Dennis's
stuff.
I've sent a query to someone on the inside; I'll report back
if I find the answer.
It might be worth trying the Wayback Machine in the mean time.

No, there's a huge one around, something like 4000x3000 pixels.
Also, Dennis is the bearded one standing, and Ken is the beardless one
sitting, to answer Jason's question.

Hi,
I'm currently reading J. Lion's commentary of Unix Code Level Six. It
is the most useful commentary to operating system kernel I have ever
read.
It would be really useful to also have the source code of SVR4 kernel
for Intel x86. Does anyone have that?
