Blah, blah, blah...

I was just searching through the archives on another topic and didn't
see anyone mention this possible option. I haven't tried it in Centos-3,
but I know in rhel3 you have to boot using "linux update" to get it to
do an upgrade rather than a clean install. That is mentioned in the
rhel3 documentation, however not very prominently. They discourage its
use. Does anyone know if that option is available with Centos-3?
