This will become very complicated.  There also needs to be a layer to
support a type handler for each slicing type (dsinit() is only for DOS
partitions and shouldn't be called directly).  There also needs to be
a layer for unslicing (striping).

Note that slices are supposed to be machine-independent and support for
foreign labels as labels was not planned for.  I hoped to handle all
foreign labelling schemes by converting them to slices.  This would
require more slice bits, not more partition bits.
