Fred, I just got a raspberry pi 3 for the sole purpose of installing Raspberry Pints, so I would love to try your SD card image, if you've got a second to pm me the link. I'd be more than happy to give any feedback/support you need to make it work better.
Just got all my stuff from Kegconnection, can't wait to build the Keezer! Great giveaway, by the way. Here's hoping! I'm new to these forums, but I'm on r/Homebrewing constantly, and this forum is always a great reference for information.
