Assuming that you have created a Kickstart configuration file to automate the steps through the Anaconda wizard that guides you through the installation process, you should copy this file to the NFS export at the path point defined in the PXELinux configuration file:
# cp /tmp/ks.conf
/srv/install/ks.config
Substitute /tmp/ks.conf
with the path
to your predefined Kickstart configuration file.
Refer to Section 4.2, “Using Kickstart to Automate Installation Options” to learn how to create your own Kickstart configuration file.
