facter-debuginfo 1.6.5-4.fc18 is empty. Maybe the debuginfo package needs to be explicitly disabled since the changes in 1.6.5-3?
You are correct Ville. I should have caught this. Thanks! facter-1.6.6 should be landing in a week or so. I'm inclined to fix this in rawhide now and pull it in to the fedora and epel branches with 1.6.6. Will that cause any trouble?
