But Tanenbaum explicitly said he would not write a 386 version of Minix for the reason I gave above. > What I've heard is that Minix was meant for teaching.

But I think the true reason was that he just got fed up with Minix, and wanted to get on with other things. > Those who wanted Unix on their PCs used Minix because it was the only > Unix-like OS available for PCs.

What I should have said is that Linus was not dissatisfied with Minix in the sense that he didn't think it was very good. He was dissatisfied - and so were lots of other people, including me - that Tanenbaum refused to continue development in a rational way, by using the facilities available in the 386. He could easily have done this, and if had done we would all be using Minix today instead of Linux. In my opinion, Minix code was far better than Linux code. But Tanenbaum lacked the "common touch" that allowed Torvalds to get a large number of clever people (like Alan Cox) to write code _with_ him rather than for him. Tanenbaum's setup was very different, with the Master (himself) assigning coding tasks to his students. -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
