That got my attention. What backwards incompatible thing is it that I simply cannot turn off for the overlayfs that I use as root fs? Now, we don't boot straight into the overlay as root fs, buy we do pivot it in early enough. If you are somehow suggesting that overlayfs as root fs is not something that needs considering you need to think again. We depend on it, and I will flag any regression that we are walking into. But hopefully you just messed up the negations, and you meant that we *can* simply turn <whatever> off?
