and customize their package updates for their particular version, rather than upgrade their
systems to a new update version that installs new software, hardware drivers, and features on
production systems.
For example, administrators can standardize their desktop systems to Red Hat Enterprise Linux
5.1 for x86, while managing servers on Red Hat Enterprise Linux 4.5 for AMD64 and EM64T.
Administrators can stay on their version for the duration of the EUS support lifecycle, assured of
the behavior of their software version. Additionally, administrators can install critical software
updates without introducing bugs from untested new features or software.
6.1.2. Child Channels
A child channel is a channel associated with a base channel that contains extra packages. For
instance, an organization can create a child channel associated with Red Hat Enterprise Linux 3
for the x86 architecture that contains extra packages needed only for the organization, such as
a custom engineering application.
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. Further,
RHN Satellite Server and RHN Proxy Server customers have channel management authority.
This authority gives them the ability to create and manage their own custom channels. Refer to
the RHN Channel Management Guide for details.
Channels can be further broken down by their relevance to your systems. Two such lists
emerge: Relevant and All.
6.1.3. Relevant Channels
As shown in Figure 6.16, “Relevant Channels” , the Relevant Channels page is shown by
default when you click Software Channels in the left navigation bar. It displays a list of
channels now associated with your systems. Links within this list go to different tabs of the
Software Channel Details page. Clicking on a channel name takes you to the Details tab.
Clicking on the number of packages takes you to the Packages tab. Clicking on the number of
systems number takes you to the Subscribed Systems tab. Refer to Section 6.1.6, “Software
Channel Details” for details.
