--------------------------------------------------------------------------
Another test was made with GRUB 2 by downloading
{{{
bzr branch http://bzr.savannah.gnu.org/r/grub/trunk/grub
}}}
Before building GRUB 2, the file
{{{
util/grub-mkrescue.in
}}}
was edited to replace in the options of the xorriso command:
{{{
--protective-msdos-label
}}}
by
{{{
-partition_offset 16 -no-pad --no-emul-toc
}}}
Then GRUB 2 was built and installed.
The resulting image from
{{{
./grub-mkrescue -o image.iso
}}}
was put onto USB stick. It passed the same tests on Debian
as above RIPLinux example. It boots to a GRUB prompt.
Due to options -no-pad --no-emul-toc the image is about 300 kB smaller than
the image produced by original grub-mkrescue. Else it would have grown by
about 130 kB.

Open questions:
- Shall the partition of an isohybrid image be marked bootable ?
