This is still missing docs about how to interpret the contents of the "statusbin" file. "components downstream" -> userspace. I think we can start with the code review. Could you also provide a sample of the attribute files? I'm especially curious about the different instances of the sure-start attributes, including current_value, possible_values and the auditlog properties. Also is the userspace component for this published somewhere? If so it would be useful to refer to it from the commit message. Thanks, Thomas
