makefs vs. mkisofs
------------------

directories:
* root:
  - built root filesystem with packages (i.e., /usr/local)
* root_makefs:
  - create iso by using makefs(8) with RockRidge extension, i.e.,
    > makefs -t cd9660 \
	-o rockridge \
	-o label="DragonFly_v6_5_x" \
	-o publisher="The DragonFly Project" \
	-o bootimage="i386;boot/cdboot" -o no-emul-boot \
	-o bootimage="efi;boot/efiboot.img" -o no-emul-boot \
	../dfly_makefs.iso .
  - mount iso
  - cpdup
* root_mkisofs:
  - create iso by using 'mkisofs -J -R', i.e., with RockRidge and Joliet extensions, i.e.,
    > mkisofs -R -J \
	-o ../dfly_mkisofs.iso \
	-b boot/cdboot -no-emul-boot \
	-eltorito-alt-boot -eltorito-platform efi -eltorito-boot boot/efiboot.img -no-emul-boot \
	-V DragonFly_v6.5.0.804.gXXX .
  - mount iso
  - cpdup
