These are duplicate values (although they don't do any harm).

This value *is* required.  The Hurd has a re-implementation of the
ext2/3/4 file system, which is very limited.  One of its limitations
is the block size must be equal to the page size (and it only works on
x86.)   So the "blocksize = 4096" is required so that:

	mke2fs -o hurd /tmp/foo.img 1024

will use a 4k block size even for small file systems.
