Hmmm, yes.  This works.  When do file systems get unmounted and
how does this affect something like:

	cgd
	 |
	 V
	vnd
	 |
	 V
	ffs
	 |
	 V
	raid

?

Does this pose problems that we'll need to solve?

It might be worse to consider raid on cgd on vnd on ffs.  The raid's
shutdown hooks will be run [potentially?] after the ffs is unmounted.
