I think that disklabel(8) ought to be able to write the label in all
formats on any format without requiring any kernel code.  It should
probably overwrite any old label by default as well.
Then the kernel can be changed to play 'hunt the disklabel' for reading
and have the code that writes labels removed entirely.
(The 'write label' code would need to be in (say) libutil, so other
programs can use it.)
