In article by Tim Shoppa:
This brings up a question: should fixes (and I mean
fundamental fixes
like Y2K ones) be incorporated back into the boot images in the archive, or
should they be left in their "pristine" state? (Yes, i know, some of
those boot images aren't quite so pristine.)
I'd agree to both. Mind you, once you start patching, where do you stop?
We could bring V6 up to being POSIX compatible with an ANSI C compiler :-)
Seriously, at one stage I did think of trying to check-in every version of
UNIX we have into a single CVS repository. Problem is, files have moved
around, and I want to leave gaps just in case we ever get the missing versions.
As long as we're on the topic, which versions of
Unix had the C
compiler recognize when it was recompiling [/bin/login] and put a back
door in for the developers?
I might ask Dennis for the details. From memory, the binaries never got out
of the Labs, and it would have been around the time of V6. Also from memory,
this was the topic of Ken's speech when he won the Turing award. I wonder if
the article is lying around somewhere.

Ken's speech "Reflections on Trusting Trust", was published in the
Communication of the ACM, Vol. 27, No. 8, August 1984. It describes this
"trojan horse" in great detail. But I do believe from this article that
it was an example of what could be done, not necessarily something that
was ever released into the hands of the public.
