This means, that from the day the new version of Smolt hits all the repos, it will take anywhere between 28 to 31 days for all the data to be considered 'current', assuming they all upgrade that day. I hesitate to use that term, because there will still be a number of machines that are considered 'stale' and they'll have null data for SELinux as well. In other words, ignore all percentages. The only information that you will have the actual number counts.
I apologize that I haven't had the time to fix all the ugly reporting issues we've had. Man hours aren't cheap.
