What if I put /boot and /boot/grub in different sub volumes? How do I set
variables then in order to correctly load additional modules from $prefix
and yet load correct kernels? This convoy is needed in order to load
several linuxes from the same btrfs (think installing v1 then making a
clone and upgrading one of them to v2).
