I see you are using initrd there. I am not at all sure about this, but I think the situation is a bit different with initramfs because it's not a 'real' filesystem. I could even imagine it's possible to return to the initrd at shutdown, but I think with initramfs this won't work. Please correct me if I am wrong.
