# This script, ("loadclouddata"), is a sample xCAT post script for 
#	upload the openstack-cookbooks, roles, enviornment to the 
#       xCAT chef-server node, and then create the chef-client 
#        nodes, and then assign the role and environment name to the
#       chef-client nodes  
#
#	Make sure your script is executable and that is is in the 
#	/install/postscripts directory on the xCAT management node.
#
#	You must add the script name to the list of scripts that 
#	must be run at install time,  or use it with updatenode.
#
# 	To use this script you should make sure it gets run after the 
#	"mountinstall" script or any other scipts that may need to use
#       scripts in the /install directory.
#	
#	For example, to get it to run after the "mountinstall" script you
#	could set the "postbootscripts" attribute of the chef-server node
#	definitions as follows:
#
#	chdef -t node -o chef-server postbootscripts="mountinstall,loadclouddata"
