Well, it seems that I did not diff with the right file so that the patch I
posted had a little error.

This new patch will fix that, and will add some comments in the headers.
Moreover, I've patched the readme file, for you, Thomas, because
you`re worth it ;)

      format       : Always format this partition even if preserve
      reiser	  : create a reiser file system, not an ext2
 
 The order of the extra options is not relevant. For more information
 see mke2fs(8).
 
+Thus, we have the following interactions between -j, ext2 and ext3 :
+<no option> : an ext2 fs flagged as auto in the fstab
+-j          : an ext3 fs flagged as auto in the fstab
+ext2        : an ext2 fs flagged as ext2 in the fstab
+-j ext2     : an ext3 fs flagged as ext2 in the fstab
+-j ext3     : an ext3 fs flagged as ext3 in the fstab
+ext3	    : an ext2 fs flagged as ext3 in the fstab !!BAD!!
+
+The use of auto in the fstab for ext3fs enable a non-ext3 enabled kernel or 
+tool to cope with these partitions.
