With CentOS 8 released, it is time to start integrating it and see what works and what doesnt! First was spacewalk.
We are running 2.9 and there is no repository for 2.9 for that version. So we have to use their nightly repo. The following changes were needed to get it to work (assuming that the new centos 8 channel/keys/repo are setup in Spacewalk). I would paste the snippets from my faviorite automation tool, but if you can read this you can translate it :) dnf config-manager --add-repo https://copr-be.
