Linux Distributions Supporting SELinux
Currently only Fedora Core supports SELinux by providing it as an integral component that is installed without special effort on the part of the installing user. However, Red Hat has announced that Red Hat Enterprise Linux 4 (RHEL 4) will support SELinux. The RHEL 4 implementation of SELinux is expected to closely resemble the one in Fedora Core 2.

Fedora Core is a Linux distribution sponsored—but not supported—by Red Hat that uses the distribution as a test bed for new technologies being considered for incorporation in Red Hat’s supported distributions, such as Red Hat Enterprise Linux. Fedora Core is freely available at http://fedora.redhat.com. Unlike Red Hat Enterprise Linux, which contains proprietary components, Fedora Core is fully redistributable under the terms of the GNU GPL.

Disables SELinux.
- Warn
Enables SELinux to log, but not prevent, attempted violations of the SELinux policy.
- Active
Enables SELinux to fully enforce its policy.
