[luau] ics412: operating systems

[Charles Lockhart]

Don't know how many people know this, but this semesters ics412, operating
systems class, is (maybe was) based on Linux (the main reason I'm taking
the class).  I thought it was a pretty good idea, an introduction to
operating systems using a real operating system.  Apparently the class
(and I guess many os classes at other universities as well) is typically
based on os simulations, and that previously ics412 was taught using an os
simulation written in Java.
