People really shouldn't be doing that.  It wastes time copying unused
space and causes problems with duplicated UUIDs, as well was
preserving any existing filesystem fragmentation, and of course, the
size matching issues.  Trying to do this with a disk with mdraid or
lvm partitions on it will really confuse the hell out of mdadm/lvm.
