breezy ipod issues

[Chris Peterman]

Well, the first one I can answer. It was most likely Standard Error (stderr). 
Without going too much into it, there are 3 main "data streams" available to 
any app (file streams don't count). StdIn (Standard Input, normally the 
keyboard), StdOut(Standard Output, normally the terminal), and StdErr(Also 
normally the terminal, but the data isn't buffered like with Stdout. Think of 
Stdout filling a cup with water and drinking it and stderr as drinking the 
water right from the faucet). 

"CTRL+ALT+F1" is properly called Virtual Terminal 1 or tty1 for short. Its 
appearing because someplace in the code is telling it to go to StdErr and 
nothing had control of tty1 so it just went there.

I hope this helps a little :D
