[4] does have states for the flow you've described above, mostly. Also, 
the state set enums can have specific meanings once they're associated 
to a sensor (or an effecter), in fact they have to be interpreted in 
conjunction with the sensor or effecter. So for eg a state enum such as 
"boot started" can be associated with both a logical sensor monitoring 
the hypervisor boot and a logical sensor monitoring the OS boot.
