No, that's more generic metadata.  User-data is specifically the base64
encoded chunk that is uploaded by the instance launch process.  It is
downloaded by cloud-init, and dealt with separately to how cloud-init
deals with root keys or hostnames or any of the other pieces of
information available in metadata.  I can see how it's easy to become
confused by the poor naming and the overloading (eg, openstack has 3
completely separate things all called 'metadata').
