xdelta for DVD ISO-images

[Florian La Roche]

The following is done for specifix for DVD images. Maybe this can
also be implemented for FC.

greetings,

Florian La Roche



We ship the Specifix Linux distribution on two CD-ROM images
per architecture.  If you have a DVD burner and want to create
DVD images, we have supplied xdelta version 1 files created from
concatenated CD images to a DVD image.

To create the DVD image, download the two CD-ROM images and the
xdelta for your architecture, and run these two commands:

cat specifix-linux-0.23-<arch>-disc1.iso specifix-linux-0.23-<arch>-disc2.iso > spx-merged.tmp
xdelta patch specifix-linux-0.23-<arch>-cd-dvd.xdelta spx-merged.tmp specifix-linux-0.23-<arch>-dvd.iso

Substitute <arch> for your architecture. Burn the resulting dvd.iso
file to a dvd:

growisofs -Z /dev/dvd=specifix-linux-0.23-<arch>-dvd.iso

If you are not yet running Specifix Linux, and if your distribution does
not include xdelta 1, you can get xdelta 1.1.3 from
