# Purpose:	This script will go through and setup a base CentOS 7 minimal OS         #
#			install so that it is ready to be made into a VM template or cloned.     #
#  			It will also install the first_boot_setup.sh script so that              #
#           the VM will configure itself as required on firstboot                    #
#                                                                                    #

### Useage
#
# After creating a new minimal VM with CentOS 7, and creating only a root user account
# No additional packackages or configuration is to be done - this script will do it
# Attach the iso containing this script and run it. Simples
