Absolutely. For example, if I build an image on my build server, and
run bmaptool create there, it finds the holes and is able to generate a
correct bmap file. If however, I first scp that image file locally, and
then run bmaptool create, it finds no holes because scp-ing the file
has replaced the holes with actual data.
