Absolutely, and furthermore I'm wondering what's happening in the
case where the drives have 4096 bytes blocks; I suppose then sunit
should be expressed as a number of 4096 bytes blocks, and what about
swidth ? the hell if I know :) This is also probably a nice little nest
of coming filesystem bugs to be hatched :=)
