There are more problems than just the checksum. Using different compression would break the iso layout of the disc. Sure, you could have recreated this as well but then what would finally be the point in distributing iso images at all?
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 :-? - -- Cheers, Carlos Robinson -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (GNU/Linux) Comment: Made with pgp4pine 1.76 iD8DBQFEVqBbtTMYHG2NR9URAjNRAJ0Sd0vJZimweO+8qSIyuZJCg39IqACbBjoh fFphrhSGIm9/r9mXQID7/GI= =7a/Z -----END PGP SIGNATURE-----
