But that doesn't mean the farmers shoudln't be able to work on the system itself if it is broken, using readouts from the system as a guide to fixing it. This might mean, however, that instead of being able to fix the software itself, they have to buy a new drive, exchanging in the old one in the process. This small bit is a reasonable request because folks can be highly motivated to cheat otherwise.
