Oh, another thing - I've always thought that every course on unix-like 
systems should touch on what the fork() and open() system calls do, sort 
of like learning to count to 10 before memorizing math formulas. If you 
understand that every process except init is fork()ed from a running 
parent, that environment variables and open files are inherited (because 
the child/parent share the COW memory), and the security checks that 
happen in open(), you can pretty much deduce the rest of the system 
behavior (well, except for selinux...).
