Those that are using RHN Classic management functions via the web or RHN Satellite 5.4 and earlier or Red Hat Satellite 5.6 and later should choose RHN Classic for now.
Customers using older versions of Red Hat Enterprise Linux must continue using RHN Classic. System can also be registered via the command line by using the "subscription-manager" command.
Red Hat Enterprise Linux starting with versions 6.1 and 5.7 introduced a new Red Hat Subscription Management (RHSM) service, which runs in parallel with Red Hat Network (RHN) Classic.
Users that are new to Red Hat or would like the enhanced subscription information and improved content access should use RHSM.
If one or more packages or package globs are specified, Yum will only update the listed packages.
