For fonts we had the same problem : many font packages want to install fontconfig rules, they can not really be interpreted by anything other than fontconfig, but we didn't want to force use of fontconfig whenever a font package is installed. The solution was to move /etc/fonts/conf.d to the filesystem package, and declare any package could drop files in there, but they would only be interpreted on a system with fontconfig installed -- Nicolas Mailhot -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
