# We use dd(1) to write the scraper utility directly to a disk
# device. Most disks must be written in multiples of their sector
# size, which is typically 512. In order to make sure the last 512
# bytes is written out, we want to append an extra 512 bytes just
# in case our binary image is not exactly a multiple of 512 bytes
# in size. We know that the boot block image is exactly 512 bytes,
# so we stick an extra copy at the end as padding.
