Yes, certain packages have to be modified to remove RedHat branding. Certain other packages have to be modified to point to CentOS repositories, etc. In extremely rare cases there may be a critical security vulnerability which the CentOS developers feel merits an update before RedHat release theirs, in these cases the updated RedHat package will take precedence once it is released. CentOS is, in as much as is reasonably possible, a clone of RHEL, but it cannot be an exact duplicate of all the packages. Peter
