Creating the CentOS Kickstart File
The Kickstart file is a text file, containing a list of items, each identified by a keyword. This file can be generated using the Red Hat Kickstart Configurator application, or it can be written from scratch. The Red Hat Enterprise Linux installation program also creates a sample Kickstart file based on the options selected during installation. It is written to the file
/root/anaconda-ks.cfg in this case. This file is editable using most text editors.

It is highly recommended for ease of use that the system image source trees be kept under 1GB in size.
