Aactually, the bug is in vfat not in qemu-img.
qemu-img correctly uses ftruncate() which is suppose to make the file sparse
if the underlying filesystem supports it, but it should fall back to adding
zeros
to the end of the file. On vfat you aren't able to seek past the end of a file
period, so this doesn't work.
Probably qemu-img should just bail out in this case (as the other disk formats
should work fine and you can always use dd). The 2nd patch I released does
this - the error message just needs to be made more accurate.
