In all fairness...

put "install ipv6 /bin/true" in modprobe.conf, then run "chkconfig 
ip6tables off" and that's it - after a reboot, you're IPv6 free...

This is just not worth changing defaults over. IPv6 is the future 
(whether you like it or not), so lets just leave it there to be as ready 
as possible when the ship sails. I haven't swithced to IPv6 either, but 
it takes less that 30 secs to disable it on a newly installed system. 30 
secs that I can easily spare on this. If you do mass installations. 
Letting kickstart implement these changes will add 0 seconds to the 
install time.
