Description of problem:
When I run /etc/rc.d/init.d/iptables restart I break ntpd.  I suggest
the iptables script on (re)start checks the status of ntpd, and if
ntpd is running it should restart ntpd (or at least print a warning
message)

Version-Release number of selected component (if applicable):
iptables-1.2.7a-2

How reproducible:
always

Steps to Reproduce:
1. /etc/rc.d/init.d/iptables restart
2. wait awhile
3. /usr/sbin/ntpq -c peers
  
Actual results:
ntpd losses sync with upstream servers

Additional info:
Should be trivial shell script change. /etc/rc.d/init.d/ntpd status
exits with an error code if ntpd is not running. I could do it myself
if asked.
