That might come in handy.
If you do, please attach it to that BZ,
or post it here as an attachment and I will.
For the record, I did this:
(using GNU cp and GNU tar for their sparse-related options,
and with 634764 being the (size in bytes of F) / 1024)
dd if=/dev/zero of=F bs=1K seek=15 \
count=$((634764-16)) conv=notrunc
cp --sparse=always F AppleBoot.img
tar jcvSf - F2 > AppleBoot.img.tar.bz2
I'm pretty sure I could have trimmed 1 or 2KiB more off each end,
but it wasn't worth it.
