bool "ext2/3/4 root filesystem"
fs/ext2: use mkfs to generate rootfs image mkfs is now capable of generating rootfs images. Use mkfs instead of genext2fs. If not set, we now let mkfs calculate the block size and the number of inodes needed. This change also adjusts the options to meet those of mkfs. Notes: * Passing a null inode number to mkfs triggers its automatic calculation. * Passing a fs-size with no unit suffix to mkfs is interpreted as using 1K block size.

The default is "-O ^64bit", i.e. disable 64-bit filesystem

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.

Do compress the ext2/3/4 filesystem with bzip2.
Patch from gtj -- http://bugs.uclibc.org/view.php?id=39 0000039: Adds options to ext2 filesystem creation Adds ability to specify block and inode counts, reserved blocks, permissions squash and device table in the configuration. Also adds capability to gzip output and to copy the resulting image to a secondary location like a tftp server's root directory.

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.
