Note that Quozl's version also works better on images created with
image-builder tools which delete files during the image creation
process (ie, on just about anything which involves mounting the
filesystem image during the image creation process; as opposed to
(say) squashfs, which is a read-only filesystem created all at once
from a filesystem tree at the very end).
Deleted files will leave 'dirty' blocks which are not zero but can
still be safely skipped.
