your keyword, select the criterion to search by, and click the
Search
button. The results appear at the
bottom of the page.
4.6.5. Packages
A package is the smallest essential ingredient of any Red Hat Linux system. Packages, commonly
known as RPMs because of their oversight by Red Hat Package Manager, are the pieces of software
that, when installed, enable your system to operate. Packages are grouped by channels to help you
more easily determine which are applicable to your systems.
These packages can be retrieved in one of two ways: by direct install or through download.
4.6.5.1. Package Install
Only packages included in a system’s subscribed channels can be installed or updated on that system.
Important
If you use scheduled package installation, the packages will be installed via the RHN Daemon. You
must have the RHN Daemon enabled on your systems. Refer to Chapter 5 Red Hat Network Daemon
for more details.
