I have created a rpm file that modifies the /etc/sysconfig/iptables when installed (add rules to block internet for all users except one.). It works well.
I include this rpm-file in my kickstart file, but no changes in /etc/sysconfig/iptables are made. When I boot up on the live iso I find my modified iptables-file in /etc/sysconfig/iptables.old.
How do I make changes in /etc/sysconfig/iptables from a kickstart file (livecd-creator)?
