Chapter 6. Entitlement
When registering a system with firstboot, the RHN Classic option is checked by default in the Subscription part.
It is now possible to automatically regenerate new entitlement certificates after the renewal of a subscription. Prior to this enhancement, customers were required to manually regenerate the certificate to continue to receive software updates and other subscription services. Automatically regenerating a certificate minimizes service interruptions. Users are also notified of cases where auto regeneration of certificates was not successful. For more information, refer to https://www.redhat.com/rhel/renew/faqs/.
Red Hat Enterprise Linux 5.8 adds support for subscription stacking. This allows users to combine a set of subscriptions on a single machine in order to become compliant. For more information on subscription stacking, refer to the Red Hat Enterprise Linux 5 Deployment Guide.
Red Hat Enterprise Linux 5.8 includes a new tool to migrate RHN Classic customers to the certificate-based RHN. For more information, refer to the Red Hat Enterprise Linux 5 Deployment Guide.
