Yellow dog Updater, Modified

From Linux@Duke [1]

Yum is an automatic updater and package installer/remover for rpm systems. It automatically computes dependencies and figures out what things should occur to install packages. It makes it easier to maintain groups of machines without having to manually update each one using rpm.

Yum is based off of Yup - The Yellow dog UPdater. Yum has a bunch of new features though.

If you're using K12LTSP 3.1.0 or newer, yum is already installed and configured. As root, just "yum list updates" to see what updates are available. "yum install foo" to install foo, as long as foo is in one of the repositories listed in /etc/yum.conf or /etc/yum.repos.d/.

The first time you do anything w/ yum, it will download RPM headers for all of the packages you don't have installed, which amounts to 9.4M on my K12LTSP 3.1.0 server. After that, it will just d/l headers for new packages.
