    • One other thing I think the free software community has learned as a whole that will play a prominent role in making HURD usable and popular is how to port an OS across architectures. BSD lite started out as an Intel OS. I think. (Actually, it was a descendant of a VAX OS, which was a descendant of a PDP OS. But who's counting?)

    BSD started life as a set of patches to AT&T V7 Unix and it initially ran on PDP 11s. AT&T had that same kernel running on several different architectures at that point

    • Well, I knew there was a lot more porting involved in there that I was leaving out. I specifically knew about Motorola chips and some of the other things you mentioned. Yes, UNIX has always been very portable. I consider the "free software community" to be a descendant of that same group that was doing that work back then.

      I do know that NetBSD reached new heights of portability. They reached the point a long time ago when a single driver could be used in the OS on different architectures. Very modular, architecture specific elements very encapsulated. And I think Linux is a great example of getting to that point through refactoring, after ignoring the "need" for portability in the early days, when it would have been counterproductive. I was really getting at the extreme programming principles in action more than anything else.

      Definitely not trying to discount the portability work in UNIX, which in fact predates not only the modern free software/open source movements, but also predates me! :)
