Chapter 6. Registering the System and Managing Subscriptions
The subscription service provides a mechanism to handle Red Hat software inventory and allows you to install additional software or update already installed programs to newer versions using the yum or PackageKit package managers. In Red Hat Enterprise Linux 6 the recommended way to register your system and attach subscriptions is to use Red Hat Subscription Management.
It is also possible to register the system and attach subscriptions after installation during the firstboot process. For detailed information about firstboot see the Firstboot chapter in the Installation Guide for Red Hat Enterprise Linux 6. Note that firstboot is only available on systems after a graphical installation or after a kickstart installation where a desktop and the X window system were installed and graphical login was enabled.
