I use a dual boot RH9 / FC2 with apache2 for web apps. development and just received a notification from RHN that one of my servers is marked for deletion because of inactivity. I logged on and found the one server I did register as a Demo, the RH9 and three other servers, FC2 installs that I did not register using my dyndns domain name.
When I try and run up2date on the RH9 install it says everything is updated and if I am not mistaken, they quit updating RH9. Is this anything to worry about and are the FC2 servers automatically added here as I did not add them?

RH 9 is out of support and no official updates have been provided for a year. I'd suggest that you either go to fedoralegacy.org to get security updates from them, or if you are running RH 9 because of it's similarity to RHEL 3 then take a look at the CentOS project.

Thanks for the CentOS link. It looks like I may find what I need there.
