I don't think the BSD kernel when adopted had much, if any,

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.

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...
