Aah!

Did you realize that such an option exists, and is added by my patch
set ? :-)

See:

  http://git.free-electrons.com/users/thomas-petazzoni/buildroot/commit/?h=x86-stuff&id=b01db75a6d7165005f9fb069c340f4206160c7f5

which adds the BR2_TARGET_GRUB_FS_SUPPORT option. You simply need to
change it from "ext2fs fat" to "ext2fs fat iso9660" and that's it.

Can you confirm that it works for you?

Also, could you share how you build your ISO image with Grub ? I would
be interested in adding these details to the Config.in help text, as I
did to explain how to create a disk image that has grub installed.

Thanks!

Thomas
