Description of Problem:


Version-Release number of selected component (if applicable):
By default, /etc/init.d/ipchains loads the ipchains module even if
/etc/sysconfig/ipchains does not exist (the user specified no firewall
during the install).

Since both /etc/init.d/ipchains and /etc/init.d/iptables are both run
during bootup by default and iptables will exit if the ipchains module has
been loaded, we need to add a test for existance of /etc/sysconfig/ipchains
and if it does not exist, exit before loading the module.

How Reproducible:
every time

Steps to Reproduce:
1. Install and run rc1
2. create an iptables configuration but it will not run
3. 

Actual Results:
by default, ipchains module is loaded

Expected Results:
ipchains is loaded only if /etc/sysconfig/ipchains exists

Additional Information:
	Of course there is the case when both /etc/sysconfig/ipchains AND
/etc/sysconfig/iptables both exist but ??
