I have a silly question:
WHY do you need to "scratch" install on Leap, when Vicibox is a Leap installation already? (Doesn't really matter, but proper etiquette would have been to include this information ... even if the reason is "our new corporate policy.)
And while answering, remember that we often find a solution outside your original pathway ...
Next up: You already have the scratch installation method on the Vicibox install CD. When you type "os-install", the script that runs will install the OS and necessary packages. Reading that script would allow you to duplicate the fire.
Then after the OS is installed, you type "vicibox-install". Guess what? That, too is a script on the CD and also on the resulting installed OS's HD which has the rest of the install information.
If your intention is to replicate this in SuSEStudio, however, I have some slightly "less than optimal" news: Kumba does not provide this. That portion is proprietary. The source code for the entire installation, however, is fully available on the CD you download from Vicibox.com
