>Description:
I have launched e2fsck (from e2fsprogs package) on an UFS2+SU filesystem and it did the "corrections" to the filesystem!!!
>How-To-Repeat:
Launch e2fsck on UFS filesystem and see it does not stop because FS is not EXT2.
>Fix:
Do not allow e2fsck to work on filesystems other than EXT2!
