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,
I used 5 konsole windows running concurrently to create the 5 CDs and it took me 1.5 hours to create the new iso's. This is on a Xeon 2.4Mhz HT with 768M of ram. Try running two concurrently sometime and see if it runs faster. -- Ken Schneider UNIX since 1989, linux since 1994, SuSE since 1998
