Judging from his biography, he should be skilled when he started working on it, but I don't think he knew very much about OS and compilers because these were pretty tough topics.
Also it took him around 2 years to get a basic port done (75-77) with a bit of help in the first year.
Anyway I believe there were a lot of head banging but he came out in pretty good shape.
Damn wish I had the time to do something like this. I'd like to rely ONLY on printed books and specifications for such a project (say port xv6 to some 32-bit arm processor), or something even simpler. But I really don't have the capacity sadly.
