Hi Tim,

How are you making these changes? Are you doing so in the kickstart, in a %post section? If so, that probably won't work, because your code might get run before the code that sets the default firewall rules.

If you want such changes to be made via your kickstart file, you need to add the commands to the end of /etc/rc.d/init.d/livesys, so that they'll be run on first boot. See fedora-live-base.ks for details on how to go about it. (In fact, fedora-live-base.ks sets up the livesys file, and then fedira-live-desktop.ks has an example of how to add extra commands afterwards by means of 'cat >> /etc/rc.d.init.d/livesys << EOF'.)

Thanks, James. That's what I was hoping. Further and better particulars will have to wait until I get back to the computer, I'm afraid.

Anything in particular?  

So far, I was I just enabling sshd (chkconfig --levels 345 sshd on), turning off the firewall (chkconfig --levels 345 iptables off)  and then "shutdown -r now".
Upon reboot, no sshd. Now I know what to expect, I can dig around more specifically.
