Remounting / with added extra layer you mean perhaps ? I tried that, but overlay is stubborn (without showing any error it stays exactly how it is)
No, I was wondering about taking the already created overlay (merge), adding new layer to that via a new overlay (merge as lower layer - i.e. part of nested overlay) and then somehow chroot to that - or similar. I have no idea beyond a thought and may not be useful.
