What is still true is that it is not defined on what environment a given 
package was built. Given the fact that a big chunk of the RHEL packages 
came directly from FC6 build on whatever was current then.

CentOS-5 is build on a CentOS-5 system that was build on CentOS-4.

Please update me if I am wrong on this :) Otherwise I need more story to 
be corrected...
