Hi,

it comes to me that i can get nearer to the Guix ISO production:

  # apt-get install grub-pc grub-efi-amd64-bin grub-efi-ia32-bin mtools
  ...
  # grub-mkrescue -o /tmp/test.iso /gnu
  xorriso 1.4.6 : RockRidge filesystem manipulator, libburnia project.
  ...
  ISO image produced: 652920 sectors
  Written to medium : 652920 sectors at LBA 0

  # ls -l /tmp/test.iso
  -rw-r--r-- 1 root root 1337180160 Dec 15 20:09 /tmp/test.iso

  # expr 1337180160 / 2048
  652920

  # xorriso -indev /tmp/test.iso
  ... no complaints ...

And with GNU xorriso 1.5.0 :

  # rm /tmp/test.iso
  # grub-mkrescue --xorriso=/home/thomas/xorriso-1.5.0/xorriso/xorriso \
  >               -o /tmp/test.iso /gnu
  GNU xorriso 1.5.0 : RockRidge filesystem manipulator, libburnia project.
  ...
  ISO image produced: 652920 sectors
  Written to medium : 652920 sectors at LBA 0

  # ls -l /tmp/test.iso
  -rw-r--r-- 1 root root 1337180160 Dec 15 20:15 /tmp/test.iso

  # xorriso -indev /tmp/test.iso
  ... no complaints ...

All looks well.

Have a nice day :)

Thomas
