Here's what it says on my DVD (it came with a magazine):
Creating installation CDs from the DVD
For SUSE, you can create writable CD ISO images for installation on a DVD drive-less machine. This can be done from within Linux or Windows. Using the Jigdo system, you can assemble CD images from the DVD contents within minutes - but you only need to run one command. Mount your DVD and enter the following in a terminal:
[tt]sh /mnt/cdrom/Distros/SUSE/mkiso[/tt]
This will create five ISO images in your current directory. Of course, you'll need to change /mnt/cdrom to another location if your DVD is mounted elsewhere. To create the ISOs somewhere else, give the path as an argument, such as:
[tt]sh /mnt/cdrom/Distros/SUSE/mkiso /tmp/iso[/tt]
Note that you should not cd to the directory on the DVD when running this script. It'll be slower because the script will be unable to open the cache file used to speed up the process. If you're short of space, you can create single ISO images (here for disc 2):
[tt]sh /mnt/cdrom/Distros/SUSE/mkiso -d 2[/tt]
If you get an error like '../../Essentials/Jigdo/jigdo-file: Permission denied', your DVD has been mounted with the noexec option, which prevents running programs directly from the disc. For security, this is implicit if the DVD is mounted with the user option. To fix this, copy the file Essentials/Jigdo/jigdo-file from the DVD to somewhere in your path - /usr/local/bin is a good choice. mkiso will then use this in preference to the file on the DVD.
Creating ISO images in Windows
Windows users can create the CDs by double-clicking on the 'winmkiso' icon or running the script from a DOS prompt. In the latter case, you should change to the SUSE directory of the CD before running the script. The resulting ISO images will be built in C:\.
