grubenv vs. diskfilter

While grub itself can be installed on diskfilter devices (LVM, Linux
MD, ...), diskfilter devices are read-only. As grubenv is automatically
assumed to be in /boot/grub, this makes it impossible to set variables
from within grub. So grub cannot reset boot once indicator, cannot save
currently selected menu entry etc.

Just looking for ideas here. Thank you.
