The following rules apply to Errata Updates:
1. Each package is a member of one or more channels. If a selected system is not sub-
scribed to the channel that the selected package is a member of, the package will not
be installed on that system.
2. If a newer version of the package is already on the system, the package will not be
installed on that system.
3. If an older version of the package is installed, the package will be upgraded.
The packages will be updated by the RHN Daemon. You must have the RHN Daemon en-
abled on your systems. Refer to Chapter 6 for more details.
