That would seem to indicate the Ubuntu Mantic installation process is
creating the bpool with zfs flags that are incompatible with grub. I
wonder if the problem is still present in Noble Numbat/24.04?
Are you able to check which zfs flags/features are set after the bpool
is created? (use `zpool get all bpool` to get flags)
You will need to backup your /boot directory and recreate you bpool with
the `-o compatibility=grub2,ubuntu-22.04 \` option, as described earlier
in this thread.
