mkzftree can compress for mkisofs, with the advantage (over tar) being
transparent decompression, ie, the kernel makes it look like normal.

However, working out where to split the filelist for multi-cd backups
might be a bit more tricky, mainly because compression makes it
difficult to predict the final image size.

What are Software Patents for?
To protect the small enterprise from bigger companies.
What do Software Patents do?
In its current form, they protect only companies with
big legal departments as they:
a.) Patent everything no matter how general
b.) Sue everybody. Even if the patent can be argued
	invalid, small companies can ill-afford	the
	typical $500k cost of a law-suit (not to mention
	years of harassment).
Don't let them take away your right to program
whatever you like. Make a stand on Software Patents
before its too late.
