I've been running ubuntu off an SDcard on the 2017 SATV 16gb model but would like to move to the local emmc drive. The user partition appears to be mmcblk0p33 (is this correct?) and if so I don't think there is an image file provided that will run the OS off this partition (assuming this is the route to running Ubuntu natively). Is there a resource where I can find a built image file for this partition, or will I have to make one (i've never made one before so I'm not sure what I would be getting myself into)?
