RightScale script to generate rails database.yml file upon server launch

	#!/bin/bash -ex
	# Create database.yml for a Ruby on Rails application
	# Storing database.yml in a source code control system with its production database credentials creates a security risk.
	# Using this script, you can take advantage of RightScale's secure credentials store
	# and generate the file when an application server is launched.
	#

	# If this is a reboot skip this script.
	if test "$RS_REBOOT" = "true" ; then
	logger -t RightScale "Skip RB create database.yml."
