Tip of the Trade: Kickstart
Red Hat's Kickstart is a versatile, easy-to-use customization tool that gets better with age. With Kickstart, Fedora and Red Hat Linux users can easily customize and replicate installations. Every installation automatically creates a Kickstart file, so one way to create a perfect installation image is to perform a custom installation, selecting exactly the desired package, then using the resulting Kickstart file to replicate it.

Fedora even has a graphical Kickstart editor, Applications - System Tools - Kickstart. But they aren't difficult to edit, as they are plain-text files with one option per line. They are found in /root/anaconda-ks.cfg. This is a short snippet from a typical ks.cfg file:

The installation files can be anywhere CD, DVD, network server, or just about any other medium. The installation is started with a boot option that specifies the location of the kickstart file. This example shows how to use a an HTTP server:
A slick way to install dozens, or even hundreds of nodes at once is to use Kickstart, PXE boot, a DHCP server and an TFTP server. For a detailed howto, see the Red Hat System Administration Guide.
