Hi,
I'm not sure if this is worth your time, but when running the 'csf -m' command on a Fedora 10 server, CSF inaccurately reports the OS as outdated. Since this is the latest version, you could add checks. That said, I'm not sure how many people run Fedora servers, and if it would be worth it to add checking for the current release version to accomplish this. Just a suggestion. The work you do on this product is outstanding.
