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.
