Sorry to hear that, living on what "they" think you ought to be able to 
live on sucks, big time.

Yikes.

One could say I had a bit of a head start on a nix like os as I've been 
running os9, now nitros9, on various trash-80 color computers since about 
'85.  Not near as much security inherent in it, and the scheduler is very 
simple but it was/is a great teacher, one of them is running in the 
basement right now.  I can safely say that the uptime for all the windows 
box's I've ever owned is probably under 24 hours, total.
Generally I build my own and the linux install dvd/cd is all they ever see 
in the dvd reader.

No, that's wrong too.  Now there's a race condition between the rm and
the mv.  Hmm, I need more coffee.
