    Description:
        This callback will be applied by util.mount_cb() on the mounted
        file.

        Deltacloud file name contains deltacloud. Those not using
        Deltacloud but instead instrumenting the injection, could
        drop deltacloud from the file name.

    Input:
        mount_dir - Mount directory

    Returns:
        User Data

        Description:
            User Data is passed to the launching instance which
            is used to perform instance configuration.

            Cloud providers expose the user data differently.
            It is necessary to determine which cloud provider
            the current instance is running on to determine
            how to access the user data. Images built with
            image factory will contain a CLOUD_INFO_FILE which
            contains a string identifying the cloud provider.

            Images not built with Imagefactory will try to
            determine what the cloud provider is based on system
            information.
