Need to grab 'user-data' as well as 'meta-data' for EC2

Notice the current code below only grabs the 'meta-data' tree from the root. It needs to also grab the 'user-data' portion

EC2_METADATA_ADDR = "169.254.169.254"
EC2_METADATA_URL = "http://#{EC2_METADATA_ADDR}/2008-02-01/meta-data"

def metadata(id='')

1. Try non-blocking connect with lite spin so we don't "block" if
2. the Xen environment is not EC2
   OpenURI.open_uri("#{EC2_METADATA_URL}/#{id}").read.split("\n").each do |o|
   key = "#{id}#{o.gsub(/\=.*$/, '/')}"
   if key[-1..-1] != '/'
   ec2[key.gsub(/\-|\//, '_').to_sym] =
   OpenURI.open_uri("#{EC2_METADATA_URL}/#{key}").gets
   else
   metadata(key)
   end
   end
   end
