In other words... Stop hack around. This is so irritating.
If disk lies about its sector size, add quirks at the layer where disk
is discovered. Don't hack ZFS, UFS, any other file system and GEOM
classes, because its easiest for you. It would be best if you could just
leave it to mav@ who knows this area and knows what he is doing. Those
drive-by hacks of yours are really doing more evil than good.
