I saw that.
However during the boot of Linino there is a prompt: "Hit enter to enter failsafe mode".
If I were to try your suggestion, there is a high likelihood that it will send linino into failsafe mode.
Someone must have solved this issue by now. Or maybe Yun's are being use more like toys or learning tools and not in a project where they need to work autonomously (at least not where Arduino/Yun interaction is required)
