I actually picked up and then put down a good looking book on Unix systems programming either by Stevens, or by someone who worked very closely with him and wrote an updated version. I think I'll scream off to the book store and track it down.
It's the updated version of APUE done by Rago (the guy who did Unix System V Network Programming; a fairly good book but with a narrow and almost obselete focus; sysv STREAMS -- a very good idea whose time hasn't come.)
