This patch adds a image with squashfs as the root filesystem. A rootfs_data partition will be generated on the first boot and placed inside the rootfs partition (just after the squashfs image). advantages: - it is possible to migrate from an existing -ext4 installation and back via sysupgrade. - existing partition layout will not be lost. - slightly smaller image size. - support for attendedsysupgrade disadvantages: - needs f2fs + tools as well. This is because fs-tools decides on the blocksize of the sdcard. So either f2fs or ext4 can get choosen as the rootfs_data filesystem (depends on the size of the root partition). - rootfs_data is placed into the rootfs partition. This makes it difficult for tools that expect a /dev/mmc0pX device. It also makes it difficult for data recovery tools since they might not expect to find a embedded partition or will be confused. For people with existing build configurations: make sure to include mkf2fs and f2fsck package into the image... Otherwise the new -squashfs image will boot of a ram-overlay and won't keep the configurations after a reboot.
