I'm creating a custom install / respin ISO with updated packages and a kickstart - starting from CentOS 6.5 minimal install DVD. I'm generally following the directions from http://smorgasbork.com/component/content/article/35-linux/128-building-a-custom-centos-6-kickstart-disc-part-1 . I can create the iso, boot, have it find the installation media (it prints "Found local installation media"), partition the disks, resolve the dependencies, and then when it gets to "Starting installation" it prompts with "Please insert CentOS disc 1 to continue". Debugging I've done so far (all but 4 result in the prompt for disc 1): 1. I've verified that the package set I have resolves all dependencies by testing the installation into a new rpmdb. 2. I've copied over the minimal install DVD contents directly, placed comps.xml in the Packages directory, and recreated repodata (using 'createrepo -g Packages/comps.xml -o . Packages/"). 3. Built on both CentOS 6.5 (with all updates) and Fedora 20. 4. Also tried to minimal DVD _without_ running createrepo (just placed the kickstart in the root of the image). This worked fine. That 4 works suggest that createrepo is at fault, but I can't for the life of me figure out what is going on. I've done this without a base url (-u) and with (using 'head -1 .discinfo). Can anyone offer some suggestions for how to debug further? Thanks - Karl
