I understand where ntp opens the ports.  But if you don't realize that
this is happening and you restart iptables for some reason without
restarting ntp then the ports are closed.

This seems like a poor way to do things.  What happens when another
application is configured like ntp and you now have to remember to
restart several applications just because the ports were closed when you
did some testing or modified your iptables rules?  Plus it could become
difficult to track down all the scripts that modify your iptables rule

I think ntp is the only one that does this currently.  Should this not
be moved to the /etc/sysconfig/iptables file and taken out of the ntp
startup scripts?
