Yum repo for Fedora 18 is finally available: http://fedorapeople.org/groups/katello/releases/yum/nightly/Fedora/18/x86_64/ Note that Fedora 18 contains Rails 3.2. So Katello will most probably not work there (I did not tried it yet). But you are free to start hacking it :) -- Miroslav Suchy Red Hat Systems Management Engineering
