[lug] RedHat 6.2 broken network script

[Bonnell, Doug]

I've been setting up a machine with RH 6.2 as a bridge
between two networks. I could manually activate IPv4
packet forwarding, but it wouldn't come up automatically
when I admin'd /etc/sysconfig/network.

Turns out that changes have been made to the 6.2 version
of /etc/rc.d/init.d/network. This script now only turns off
ip forwarding, never turns it on under the "start" option.

Below are my changes for automatic startup of ip forwarding:

++++++++++++++++++++++++++++ Old script +++++++++++++++++++++++++++++++++++
     # See how we were called.
     case "$1" in
       start)

             action "Setting network parameters" sysctl -p /etc/sysctl.conf
             action "Bringing up interface lo" ./ifup ifcfg-lo
      
++++++++++++++++++++++++++++ New script +++++++++++++++++++++++++++++++++++

     # See how we were called.
     case "$1" in
       start)

             action "Setting network parameters" sysctl -p /etc/sysctl.conf

             if [ -d /proc/sys/net/ipv4 ]; then
                     if [ -f /proc/sys/net/ipv4/ip_forward ]; then
                             if [ "$FORWARD_IPV4" = "no" -o "$FORWARD_IPV4"
= "false" ]; then
                                     action "Disabling IPv4 packet
forwarding" sysctl -w net.ipv4.ip_forward=0
                            else
                                     action "Enabling IPv4 packet
forwarding"   sysctl -w net.ipv4.ip_forward=1
                            fi
                     fi
             fi                                                   
             action "Bringing up interface lo" ./ifup ifcfg-lo

A minor annoyance, to be sure. At least the file
/etc/sysconfig/static-routes is now being processed
by the network script in 6.2 (unlike 6.0).
