In line 137 of file "10_linux":

rpool=`${grub_probe} --device ${GRUB_DEVICE} --target=fs_label 2>/dev/null || true`

The command run returns this error:
root@stream:/etc/grub.d# /usr/sbin/grub-probe --device /dev/nvme0n1p4 --target=fs_label
/usr/sbin/grub-probe: error: unknown filesystem.

The result makes ${rpool} NULL, and sets ${LINUX_ROOT_DEVICE} to "ZFS=/ROOT/ubuntu_aaodxz"

This is clearly wrong and looks like the root cause of this issue.
