I suppose you can only tell if persistence works is by making a change and see if it is preserved after a reboot. The main problem that should be solved by the initrd.gz is that it won't boot up, as far as I can understand. I only created the initrd.gz with the instructions on this page, so don't consider me an expert ;-)
