I posted this a couple weeks ago on our corporate newsfeed, but it doesn't
seem to be distributing to the outside world (again). So I thought I'd
repost it on newsfeeds.com. This is my updated of section 6.3 of the
UNIX FAQ, which hasn't been updated in quite a while.

My sources include my own memory (nearly 13 years of using, about 6 or
7 of administering), assorted documentation and books in my library,
the internet, and old issues of UnixWorld and Unix Review. Feel free
to point out errors, of which I'm sure there are many, as well as to
send me additional information.
---------------------

Quick Definitions:
UNIX: Operating system whose ultimate roots are 6th & 7th editions.
Usually contains actual AT&T-derived code (excepting 4.4BSD).
UNIX-clone: Operating system which very strongly resembles traditional
UNIXes. Usually implemented with no AT&T-derived code.
UNIX-like: Operating system which resembles traditional unix in system
calls and/or interface

[details snipped]

Wow! That's impressive; you even have Cromix in there <g>

I have a question though:
Where (in your quick definitions and/or your detailed list) do the
POSIX standard and the current Unix (TM, The Open Group) fit in?

You might want to add alt.solaris.x86 in that.

: [ Long impressive list of Unix systems...]

The Minix book is published by Prentice-Hall, not Prentics-Hall.

You may not want to get into this can of worms, but you could also
distinguish between:

Unix(tm): Unix and Unix-clone systems that carry the Open Group trademark
Un*x: Unix and Unix-clone systems that don't

Thanks for your work in compiling this list; it's going into my
permanent files right now.
