Thank you for the report!

I'm CC'ing Mathieu as he knows this part of the code much better than I
do, having overhauled the generation of disk images recently!

Below are two patches I made while investigating this.  Mathieu, does
that look like a proper fix?  It allows images to be generated, but I'm
unsure whether they'd be bootable (I couldn't successfully boot either
EFI or MBR GRUB-based disk images in QEMU).

Anyway, attached are the patches.

Thank you!

Maxim
