it was, in fact, the first version with TCP/IP.

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

TCP/IP support didn't show up until later, I think summer 1985,

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. but rather Research Unix Edition 8 having these
things.
Yes, that's what Norman said:
>> if it did, they were excised.
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 think the perceived "failings" were with sockets, not with TCP/IP.
That was what led to the misimplementation of STREAMS. My real
confusion was what they really wanted from 4.1c, but I suppose it was
the VM implementation. Can anybody comment?
