Package: grub2 Version: 2.02+dfsg1-4 I'm told that "multiboot" does not work with UEFI and "multiboot2" is needed. (Not sure if this is true only for Xen, or more generally.) I'm also told that buster's grub has enough to support booting Xen, although I have not verified this myself.
Therefore, please could you cherry pick this http://git.savannah.gnu.org/cgit/grub.git/commit/?id=b4d709b6ee789cdaf3fa7a80fd90c721a16f48c2 onto your next upload for buster ? Thanks, Ian.
