the questions I were asked were stuff like what is an inode, where are inodes stored, what is a scheduler, what is the difference between /dev/mem and /dev/kmem
Precisely what I mean by unix trivia. What's the difference between /dev/mem and /dev/kmem? I think it's memory vs kernel reserved memory, but in my 16 years as a unix admin I have never once needed to know that. If I did, I'd go look it up. That is why I consider those questions trivial: they're not fundamental, although you can make them sound like they must be.
