What does this do?

gnu/build/vm.scm make-iso9660-image already provides /gnu/store a few lines down:

    (unless (zero? (apply system*
                          `(,grub-mkrescue "-o" ,target
                            ,(string-append "boot/grub/grub.cfg=" config-file)
                            ,(string-append "gnu/store=" os-drv "/..")
                                            ^^^^

Maybe I'm missing something...

Otherwise LGTM!
