It doesn't look entirely wrong to me.  I can see that there may be
some issue with the cd0, it should probably be more graceful about
not finding a disk there.

You need to make sure that you have a post-cleanup newfs or GEOM+md+newfs
will not play.

I also fixed a buglet in the alpha-disklabel code yesterday, I can't
tell if you have that fix or not in your kernel.

Other than that it seems pretty ok to me.  Sorry about the verboseness,
it will be reduced.
