5.5. Channels and Packages
5.5.1. System List
Refer to Section 5.4.1 for details.
5.5.2. Channel List
A channel is a list of Red Hat Linux packages. Channels are used to choose packages to be
installed on a system.
There are two types of channels:
base channels and child channels . A base channel consists of a
list of packages based on a specific architecture and Red Hat Linux release. For example, all
the packages in Red Hat Linux 7.1 for the x86 architecture is a base channel. The list of pack-
ages in Red Hat Linux 7.1 for the Itanium architecture is a different base channel. A child
channel is a channel associated with a base channel but contains extra packages. For exam-
ple, an organization can create a child channel that is associated with the Red Hat Linux 7.1
for the x86 architecture and that contains extra packages needed only for the organization,
such as a custom engineering application.
A system must be subscribed to one base channel and can only be subscribed to one base
channel. A system can be subscribed to multiple child channels of its base channel. Only
packages included in a system’s subscribed channels can be installed or updated on that
system.
The
Channel List page provides a list of all base channels and their child channels. Click-
ing on the name of the channel (base or child) displays the Channel Details page. Refer to
Section 5.5.3 for details.
