# Purpose: Setup new clone with West specific info for Radisys SWMS servers.
# Author: DGL
# Revision: $Rev$
# Updated by: $Author$
# Last change date: $LastChangedDate$
# SVN URL: $HeadURL$
#
# NOTE: Run this script immedieatly after building a Radisys SWMS server from
#       the VM template.
#
# Steps this script takes:
#  Sets the IP address and related settings i the ifcfg-eth0 file
#  Sets the hostname (both short and FQDN)
