 I have no objection (though even that doesn't mean that newfs needs
 to use it) - but if we're going to do that, it needs to work regardless
 of what the filesystem the device node is located on happens to be (so
 tmpfs and nfs need changing, and lfs, cd9660 (if that supports devices at all),
 zfs, udf, and whatever else we have will all need testing (or at a
 minimum, code examination).   Then we need to verify that none of the
 layering mechanisms (unionfs ...) change things.
