Obviously Linux owes its heritage to UNIX, but not its code. We would not, nor will not, make such a claim.

We turned 3 different teams of code programmers loose on the code bases of AIX, Unix and Linux. And they came back with - independently - we had the three teams - one was a set of high-end mathematicians, rocket scientist, modeling type guys. Another team was based on standard programmer types. A third team were really spiffy on agent technology and how all of this technology was built in the first place. So the three teams came back independently and validated that there wasn't just a little bit of code showing up inside of Linux from our Unix intellectual property base. There was actually a mountain of code showing up in there.

When we take a top-tier view of the amount of code showing up inside of Linux today that is either directly related to our Unix System 5 that we directly own or is related to one of our flavors of Unix that we have derivative works rights over--we don't necessarily own those flavors, but we have control rights over how that information gets disseminated--the amount is substantial. We're not talking about just lines of code; we're talking about entire programs. We're talking about hundred [sic] of thousands of lines of code.

… even if the Hurd didn't depend on Linux code (and as far as I know, it does, but since I think they have their design heads firmly up their *sses anyway with that whole microkernel thing, I've never felt it was worth my time even looking at their code), I don't believe a religiously motivated development community can ever generate as good code except by pure chance.

Linux people do what they do because they hate Microsoft. We do what we do because we love Unix.

We're not talking about insignificant amounts of code. It's substantial System V code showing up in Linux.
