The Eighth Edition is *not* descended from the Seventh Edition.

Here's a quote from Dennis Ritchie, posted to Warren Toomey:

----- Forwarded message from dmr -----
I also got mail from Norman Wilson today about the discussion.
This is mainly to confirm and fill out details of Wilson's account.
The Eighth Edition system started with (I believe) BSD 4.1c and
the work was done on VAX 11/750s -- our group did not get
a 780 until a while later.
Most of the operating system superstructure of BSD was retained
(in particular no one (even the indefatigable Norman)
wanted to get much into the paging code. Norman is also
right that the competitor was John Reiser's (and Tom London's)
32V descendant from another group at the Labs. In structure
this system had a lot to offer (in particular the buffer cache and the page
pool were unified, but it was clear that their work was not being
supported by their own management. It was used for a while on
our first 750 and also our first 11/780 ("alice", a name that lives
in netnews fame preceding the reach of Dejanews).
The big change leading to V8 was the scooping-out and replacement of
the character-device and networking part by the streams mechanism. Later,
Peter Weinberger added the file-system switch that enabled
remote file systems and prescient things ideas like /proc). Weinberger,
as Norman said, also did a simple-minded FFS.
The TCP/IP stack wasn't very important to us then and it has a mixed and
murky history. Much of it came from early CSRG work, but it was converted
to a streams approach by Robert Morris and subsequently fiddled over a lot.
Likewise, as Norman said, the applications (/bin and whatnot) were somewhat
of a mixture. Many were the locally-done versions, some were taken
from BSD in some incarnation, some from System V.

This is the top level of the FreeBSD source directory. This file was last revised on: $Id: README,v 1.13 1998/09/13 09:38:34 markm Exp $ For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information). The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree, the most commonly used one being ``world'', which rebuilds and installs everything in the FreeBSD system from the source tree except the kernel and the contents of /etc. Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags. Building a kernel with config(8) is a somewhat more involved process, documentation for which can be found at: http://www.freebsd.org/handbook/kernelconfig.html And in the config(8) man page. The sample kernel configuration files reside in the sys/i386/conf sub-directory (assuming that you've installed the kernel sources), the file named GENERIC being the one used to build your initial installation kernel. The file LINT contains entries for all possible devices, not just those commonly used, and is meant more as a general reference than an actual kernel configuration file (a kernel built from it wouldn't even run).
