I think similar to --efi-directory it has to refer to mount point, not
to final destination; --xen-directory=/mnt will install
into /mnt/boot/xen. We do not have control over /boot/xen part.
It also means that grub-install needs to strip off relative path off
bootdir to build xendir on the same filesystem to get sane default.
