I normally use ext2 filesystems on floppies. After creating a filesystem with mke2fs from e2fsprogs 1.18-3 the program mount from e2fsprogs 1.12-4 fails to mount it with the message: EXT2-FS: 02:00: couldn't mount because of unsupported optional features. Fsck from 1.12-4 would find no fault with the filesystem. Is it just me? (I hope.)
