I don't think they are talking about BSD4.1a having these things, but
rather Research Unix Edition 8 having these things. Bell labs didn't
integrate them until later. I recall reading articles at the time (1983
or 1984) that they had their own notion of what networking to use
that wasn't TCP/IP due to some perceived failings of TCP/IP that
they fixed with their stuff. I recall that I read it in the library in
high school. Wish I'd forgotten that and recalled what the network
protocol was they implemented instead...

-- Adopt 4.1c BSD kernel
...
I don't think the BSD kernel when adopted had much, if any,
of sockets, Berkeley's TCP/IP, McKusick's FFS; if it did,
they were excised.

TCP/IP support didn't show up until later, I think summer 1985,
though it might have been a year later.
I'm confused. 4.1c has gone down in history as the first version with
Internet code, and looking at the sources (from mckusick's CD set), I
see the network files in /sys/netinet with names very reminiscent of
current FreeBSD file names. The files have timestamps between
November 1982 and May 1983. Why should they have been removed? I
would have thought that exactly this functionality would have been the
reason why you adopted 4.1c.
Similarly, it also included FFS and (not surprisingly sockets.
I checked further back, but unfortunately the previous version on the
CDs is 4.1a, and it has no kernel code.
