This section lists the code for the /usr/sbin/clone script that clones from a golden Linux
image to a target virtual machine.
#!/bin/sh
#
# clone.sh is a script that clones Linux images. It makes use of vmcp to
# relay messages to the z/VM system and configuration files to modify
# the new image once it has been cloned.
#
# The script reads in /etc/sysconfig/clone for user setting customizations.
#
# For details on how this script works see the book:
# "z/VM and Linux on IBM System z: The Virtualization Cookbook for RHEL6"
