I mean that the checksum of the would be different, and this in turn means
that the iso would be different.

I understand that applydeltaiso decomposes the iso image in the
separated rpm archives; to each rpm it applies "applydeltarpm",
generating a new rpm; finally, it collects all those new rpm in a new
iso image, with the same boot image. The "iso" is generated anew.

However, considering that it takes 50 minutes times 5 disks = 4 hours 10
minutes to recreate the 5 CDs, it is worth considering if a lower
compression ratio, or an altogether different compression method, would be
interesting for us all. Perhaps it would mean 6 CDs, but maybe that is
acceptable :-?
