fs/ext2: add ability to build ext3/4 too Use the host-e2fsprogs to tune2fs the generated rootfs.ext2 image, and upgrade it to either one of ext2, ext3 or ext4. Since calling tune2fs may require running e2fsck (tune2fs will warn to do so when certain FS options are changed), we systematically call e2fsck. This makes the code path simpler, and as a side-effect checks that genext2fs did not generate garbage. In turn, e2fsck will unconditionally add a UUID to the filesystem, which is bad for reproducibility, so we call tune2fs again to remove the UUID. This does not require checking the filesystem. To ensure compatibility of Buildroot's .config, leave ext2 as the default. Boards' .config can override this at will. Signed-off-by: "Yann E.

bool "ext2/3/4 root filesystem"
package/mke2img: new package Currently, we are using a shell script called genext2fs, that impersonates the real genext2fs. But that script does much more than just call genextfs: it also calls tune2fs and e2fsck. Because it impersonates genext2fs, we can not easily add new options, and are constrained by the genext2fs options. But it turns out that, of all the options supported by the real genext2fs, we only really care for a subset, namely: - number of blocks - number of inodes - percentage of blocks reeserved to root - the root directory which to generate the image from So, we introduce a new host package, mke2img, that is intended to eventually replace genext2fs.sh. This new script is highly modeled from the existing genext2fs.sh, but was slightly refreshed, and a new, supposedly sane set of options has been choosen for the features we need (see above), and some new options were added, too, rather than relying on the arguments order or environment variables: -b <nb-blocks> number of blocks in the filesystem -i <nb-inodes> number of inodes in the filesystem -r <pc-reserved> percentage of reserved blocks * -d <root-dir> directory containing the root of the filesystem * -o <img-file> output image file -G <ext-gen> extfs generation: 2, 3, or 4 (default: 2) -R <ext-rev> ext2 revision: 0 or 1 (default 1) -l <label> filesystem label -u <uid> filesystem UUID; if not specified, a random one is used * Mandatory options Since the upstream e2fsprogs are expected to release a new mke2fs that will be able to generate a filesystem image from a directory, we then will be able to replace all the logic in mke2img, to use mke2fs instead of the (relatively fragile) combination of the three tools we currently use. An entry is added for it in the "Host utilities" menu, so it can be selected for use by post-{build,image} scripts. The ext2 filesystem selection is changed to select that now.
