Counting Linux users is no easy task since there is typically no requirement for users to register their installations. Yet Linux distributions do try and count users in an attempt to quantify their user base and relative footprint in the operating systems space.

Red Hat's Fedora community Linux distribution has now tallied its user base, and it's a number that on the surface would make it the largest installed base of any Linux distribution, with at least 9.5 million users and possibly as many as 10.5 million. Fedora competitor Ubuntu Linux currently claims to have 8 million users.

"The total number of users has always been an incredibly difficult number to measure," Paul Frields, Fedora's project leader, told InternetNews.com. "If you total up all the unique IP's ... on Fedora 7, 8 and 9, it adds up to about 9.5 million boxes right now."
