2BSD distribution tape, /install.ms, 1979:
----------------------------------
Second Distribution of Berkeley PDP‐11 Software for UNIX†
(revised March 1980) Installation Instructions
...
Version 6
If you have a standard version 6 UNIX system then you can just
use the binaries on the tape and avoid the bother of recompiling.
...
Other Version 6
If you have a version 6 UNIX system which has 16 bit user id’s
(such as the old systems at Berkeley) then you will have to modify the
upgrade/libretro version 7 simulator library and recompile the pro‐
grams here.
PWB and Unix/TS
If you have a PWB/UNIX version 1 system, the binaries supplied
here should work (as far as I know). If they don’t the make and cc
from PWB should be adequate to recompile to repair any problems.

† UNIX is a trademark of Bell Laboratories.
----------------------------------
Первые BSD релизы вообще ставились поверх Bell Lab UNIX v6/v7.
В общем, первые годы лабы просто обменивались кодами, и всем было немножко по иксу на торговую марку.
Например, в составе исходников 2.11BSD
# ls -l READ_ME
-rw-r--r-- 1 39 wheel 3303 Jan 29 1981 READ_ME

I N G R E S
Version 6.3
This version of INGRES runs under UNIX version seven. In its
current state it requires separated I/D space and floating point
hardware. The reason for this is that the version seven runtime
support code is larger than in version six, so we no longer fit
into a single process, even in a six process system. However,

ABSTRACT
This document contains instructions for the installation and operation of the
2.11BSD PDP-11ng UNIX system.
It discusses procedures for installing 2.11BSD UNIX on a PDP-11, including
explanations of how to lay out file systems on available disks, how to set up terminal lines
and user accounts, how to do system-specific tailoring, and how to install and configure
the networking facilities. Finally, the document details system operation procedures:
shutdown and startup, hardware error reporting and diagnosis, file system backup procedures, resource control, performance monitoring, and procedures for recompiling and
reinstalling system software.
...
Вот пример ссобщений при загрузке 2.11BSD
----------------------
:dk (0,0)unix (bring in unix from the root system)
Boot: bootdev=0nnnn bootcsr=0mmmmmm
The standalone boot program will then load unix from the root file system you just created, and the system
should boot:
2.11BSD BSD UNIX #1: Sat Jul 4 01:33:03 PDT 1992
root@wlonex.iipo.gtegsc.com:/usr/src/sys/GENERIC
phys mem = ???
av ail mem = ???
user mem = ???
configure system
----------------------------
Опять BSD UNIX =)
То есть все в период ~1979-1998 (ранее и позднее у меня нет архива)
называли ленты от UCB как BSD UNIX.
В самих лабораториях называли ленты BSD UNIX.
вот пример из 4.4BSD-Alpha:
# ls -l /usr/src/etc/motd
-r--r--r-- 1 bin man 78 Jul 15 1992 motd
--------------------------------------
4.4BSD Alpha UNIX #1: Sun Jul 19 00:00:00 PDT 1992
Welcome to 4.4BSD Alpha!
--------------------------------------
4.4 BSD-Lite без кода от Bell Labs:
-------------------------------------
4.4BSD-Lite UNIX #1: Fri Apr 01 00:00:00 PDT 1994
Welcome to 4.4BSD-Lite!
-------------------------------------
Примерно во времена 4.4BSD был уже 386BSD, и только там братьями Jolitz был сделан финт ушами ради
что бы не докопалась стая юристов - "UNIX-like"

Release Notes on 386BSD
W. Jolitz
386BSD Release 0.0:
This is 386BSD Release 0.0, the first edition from the
386BSD project. It comprises an entire and complete UNIX- <--- тут
like operating system for the Intel 80386/486 based IBM PC,
and is based almost entirely on the NET/2 release from the
University of California, which contained much of the ear-
lier freely redistributable and modifiable 386BSD source
code done by William F. Jolitz and contributed to the Uni-
versity of California at Berkeley for distribution.
Originally conceived by Bill and Lynne Jolitz in 1989,
the 386BSD project is an attempt to foster new research and
development in operating systems and networking technology
by broadening access to base technology. In cooperation with
the University of California, an advanced operating system
was redesigned by William F. Jolitz to work on common
386-based PC's for use by smaller colleges and other groups
that did not have the resources to otherwise obtain it. In
addition, starting with the NET/2 release, this software has
been released in a form that does not require license agree-
ments, non-disclosure, or other controls that would limit
it's use in undergraduate teaching programs.
--------------------------
Но все в лабах и гаражах прекрасно понимали - это тоже BSD UNIX
Но видимо сейчас не все в состоянии найти архивы и почитать исходники.
PS
Имеющиеся сейчас три ветки 386BSD - FreeBSD, NetBSD и OpenBSD имеют прямую и безусловную генеалогическую линию кода от UNIX v6/v7.
И до корпоративных войн за софт, дистрибутивы из Беркли именовались просто BSD UNIX.
Linux kernel является совершенно иной разработкой и не имеет никаких генеалогических связей с UNIX v6/v7. Не более чем подсмотрено в форточку за соседями.
GNU утилиты, в частности gcc/gdb/as/ld вообще кросплатформены, с cамого момента замысла, и написаны с нуля.
Так что де факто, дистрибутивы FreeBSD, NetBSD и OpenBSD есть прямые наследники Bell Labs UNIX,
и могут называться, если не оглядываться на стаю юристов,
FreeBSD UNIX, NetBSD UNIX и OpenBSD UNIX соотвественно.
