Running podman on an immutable filesystem (Overlayroot)

The main idea: Configure Podman to use alternative paths outside the overlay filesystem

Steps:

If already in overlay mode, break outside of it using the overlayroot-chroot command
To leave mounts out of the overlay, use recurse=0 (e.g., overlayroot="tmpfs:recurse=0") in /etc/overlayroot.conf
Edit /etc/containers/storage.conf and use alternative path values for runroot and graphroot under the [storage] section
