Nightly Rawhide LiveCD script

[Warren Togami]

Somebody asked for my crappy script to generate a rawhide LiveCD that 
can be scheduled in cron.  This script sucks.  Suggest improvements if 
you want.

One big improvement that could be written is a rawhide timestamp 
checker, so the script would run more often in cron and detect when the 
rawhide tree had actually changed, and only then generate new images. 
Otherwise you can only schedule it daily and generate images of whatever 
happens to be in rawhide at that moment, even if it hasn't changed since 
the previous day or rawhide compose hasn't finished yet.
