 Note that the pre-built Gateworks images create a minimal root filesystem as well as a partition table that assumes a specific size (matching the smallest eMMC device used on our boards). There is a script similar to the one above that runs on first-boot which expands the last partition to the extents of the device and grows the partition to fill it. See https://github.com/Gateworks/ubuntu-rootfs/blob/master/ubuntu-rootfs.sh and look for 'growpart' for details.
