Red Hat is dropping support for non-Enterprise versions of its Linux distribution.  Drop date for Red Hat 7 and 8 is end of the year.  For Red Hat 9, which I am grumpily using, the date is end of April 2004.  So now I am running unsupported OS on my server.  I am half tempted to replace it with Windows 2003 Server at this point.  Last thing on my mind is upgrading to Red Hat Enterprise.
