When a new release comes out, I generally build a custom CD image
containing i386, sparc, sparc64, and source.  I've been noticing that
my images are getting bigger, which is to be expected.  My latest image
is 704,512,000 bytes.  This is more then the maximum size of a
traditional CD and is getting near the limit for many older CD drives.
I'm wondering if we should switch to bzip2 for compressing sets in
order to reduce image size?
