CentOS 5 Networking :: Moving Interfaces At Boot?

I have a series of four config scripts which all run in sequence of each other.first occurs during the whole kcikstart thing.Kickstart then tells rc.local to run step2, which then tells rc.local to run step 3. No steps are repeated, after they are run they delete themselves from rc.local.After each step, it reboots.Step 3 is responsible for creating the /etc/sysconfig/network-scripts/ifcfg-eth1 file, and populating it. It greps ifconfig -a for the mac address of USB0.

#! /bin/bash

# Check to see if the usb nic takes eth2, if it does, move it to eth1[code]............
