Yeah, weĺl, with your method I ca't tell a user to:

	# xfs_freeze -f /mntpt
	# xfs_db -r -c 'sb 0' -c 'p rootino' /dev/foo
	128
	# xfs_db -r -c 'ino 128' -c 'p core.format' /dev/foo
	core.format = 2 (extents)
	# xfs_db .....
	.....
	# xfs_freeze -u /mntpt

i.e. using the freeze to force all metadata to disk and
prevent it from changing while doing interactive debugging
of some problem.

Yes, a one-shot freeze/unfreeze mechanism works for some
use cases. The point is that it does not work for them all.....

Cheers,

Dave.
