I agree, that's truly stupid. No-one cares about cyl/head/sect any
more, all disk I/O is done using block numbers ... and even if someone
still had a real hardware interface that used CSH addressing, that's only
an issue for that physical device. vnd is doing filesystem I/O, that's
all based on byte offsets into the file, which (faked) cylinder would be
used could not possibly be less relevant. Just fake a chs for the
purposes of the labels, etc, like real modern drives do, after which
everyone ignores that and simply uses block numbers.
