I have been using Lorax Livemedia-creator to create custom Fedora isos based on Xfce4. I recently created a custom fedora 30, but when I try to use it to install to a HD, Anaconda informs me that it is a Pre-release testing version and that it would result in an unstable system.
I commented out %include fedora-repo-rawhide.ks and uncommented %include fedora-repo-not-rawhide.ks in the fedora-repo.ks file and then flattened the fedora-live-xfce.ks, so the iso should not be a Testing version of fedora.
I have run into this problem since Fedora 28.
I would like any input from a user who has had experience rolling isos using Livemedia-creator.
