[jonaswre]

Comparison is not working '29' < '7' is true, needs to be an int comparision

Hey @jonwrede,

this looks good! Can you add this to the other places, too?

I didn't run the changes against any other distros. And not sure what the version number in other RedHat distros is. They must be all castable to int. I will comit all the changes to integrate Fedora in another pull request check #163. The next couple of weeks are busy so might take 3-4 weeks. But it will get done since i got a bunch of fedora servers running.
