Because RPMs are compressed already, and almost everything on a CentOS 
install disk is an RPM.

I tried compressing the bin DVD here with bzip2 -9 and saw a size 
improvement of less than 3%.  The cost of this tiny benefit is 2x the 
disk space during the decompression step, and half an hour of 
decompression time on a 3 GHz machine.
