Hello.

Patch below allows to protect against recursive slices creation in simlar
way as BSD class does this, ie. by calculating md5 sum of the first sector
and checking if provider below us is using metadata from the same sector.

	http://people.freebsd.org/~pjd/patches/geom_mbr.c.2.patch

It allows to remove hack for geoms with rank !=3D 1.
Comments?
