10.1 Configuring the cloner for kickstart
The installer generates a kickstart file at the end of every installation. It is based on the
answers provided during the interactive installation. This kickstart file is named
anaconda-ks.cfg and is located in the /root/ directory. This file on RH6CLONE will be used
as a template for LINUX02.
Perform the following steps:
1. Start an SSH session on the cloner (RH6CLONE) as root.
2. Start the golden image (RH6GOLD). You could log on to a 3270 session, but you can also
start it from the cloner with the CP XAUTOLOG command:
# vmcp xautolog rh6gold
Command accepted
3. Create the /nfs/ks/ directory for the kickstart file:
# cd /nfs
# mkdir ks
# cd ks
4. Copy the sample kickstart file from the golden image:
# scp 9.60.18.222:/root/anaconda-ks.cfg linux02-ks.cfg
anaconda-ks.cfg 100% 1813 1.8KB/s 00:00
# chmod +r linux02-ks.cfg
5. Edit the kickstart configuration file as follows. After the first four changes, which are in
bold, remove the comments from the part, volgroup, and logvol lines. Edit the lines in bold
to customize this kickstart for LINUX02:
# vi linux02-ks.cfg
# Kickstart file automatically generated by anaconda.
#version=RHEL6
install
reboot
