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
