Red Hat says the Fedora Core 2, test2 is available.

In case that sounds like a secret code, it's supposed to be a beta of the 2.6-based Fedora Core that supports SELinux or Security Enhanced Linux, which means the security modules endorsed by the National Security Agency (NSA). And that in turn means granular permissions for all users, programs, processes, files and devices. An application can be given just the permissions it needs to do its job and nothing more.

SELinux is supposed to be folded into the commercial Red Hat early next year.
