== Red Hat Enterprise Linux support periods

It is surprisingly hard to find this information on Red Hat's website;
you'd think the support periods for the various Enterprise Linux would
be somewhere on the product pages for each EL release, but they're
actually hiding off in the [[Security Updates
http://www.redhat.com/security/updates/]] section.

The short answer is that security updates are done for seven years after
the initial release. RHEL 4 was released Febuary 15th 2005, so security
updates will be available through the end of February 2012.

This means that [[CentOS http://www.centos.org/]] will also have
updates for that long, since they build from Red Hat EL's source
RPMs. Even if the [[CentOS]] project goes away as an organized
entity, a [[CentOS]] install can just grab the RHEL update source
RPMs and rebuild them directly.
