I managed to build my own livecd based on tumbleweed rescue. I extract config.xml from rescure iso /image and found it still using “package-lists-openSUSE-X11-cd” and “openSUSE-release-livecd-x11” from 13.1. But it have not available from download.opensuse.org.
I checked http://download.opensuse.org/repositories/openSUSE:/Factory:/Live/standard/x86_64/ and found “package-lists-openSUSE-X11-cd” is missing.
Anyone have the idea where can I found the package, or what should I do? Thanks!
