1.1. What are Kickstart Installations?

Many system administrators would prefer to use an automated installation method to install Red Hat Enterprise Linux on their machines. Red Hat, Inc created the kickstart installation method. Using kickstart, a system administrator can create a single file containing the answers to all the questions that would normally be asked during a typical installation. Kickstart files can be kept on a single server system and read by individual computers during the installation. This installation method can support the use of a single kickstart file to install Red Hat Enterprise Linux on multiple machines, making it ideal for network and system administrators. Kickstart provides a way for users to automate a Red Hat Enterprise Linux installation.
