It's far worse than that, something can become very confused:
(labels was never enabled!)

(I cannot cut&paste, so here is the gist of it:)

	# od -x fixit.flp
	0000000	0000 0000
	... <all zeros>

	# vnconfig -c /dev/vn0 fixit.flp
	# fsck /dev/rvn0
	** /dev/rvn0
	... <all ok>
	151 files ....
	#

I belive that with the merged vm/buffer, it may make more sense if vn
uses the vn_rdwr() instead of the VOP_BMAP/VOP_STRATEGY interface.

one way or another, it's hosed now on my machine...
