Much to the dismay of many Fedora users, as of Dec 12 2006, the FedoraLegacy project closed up shop and is no longer offering updates for versions of Fedora Core that had reached the end of their product life cycles (aka been EOL'd). The Fedora project has also increased the length of product life cycles from 9 months to 13 months. So for FC users that will mean you will need to reinstall at least ever other Fedora release. With all this happening, I figured this would be a good time to remind everyone to make sure that your systems are currently supported by your linux vendor or are receiving security updates some other way. If you haven't bothered to update your system or configure automatic updates, then this is a good time to start.
