I suspect a resize2fs call is needed in there. Since the SD card class in meta-raspberrypi was changed to use the actual ext2 rootfs image instead of creating a new one on the fly, this has become an issue. I would suggest filing the issue on the meta-raspberrypi github. > Also, is it possible to just build the SD image much like I do for > other devices like the BeagleBoard, albeit with different contents > in /boot?

If it's expanded it will take up 4GB minus the boot partition size so you're into a large dd again...
