And I verified, it is indeed not safe..

The script name is set by:

        script_name = os.path.join(tempdir, sprefix + "create_image." + type)

So I'd need to exclude the tempdir ($T) in order for the test to be right.. and
even then it probably should be a 'startwith' comparison?

Does this seem right to others?
