podman can be used with normal overlayfs in rootless mode (see https://www.redhat.com/sysadmin/podman-rootless-overlay).
fuse-overlayfs is only needed when the user has btrfs, aufs, zfs, overlay, or ecryptfs as the underlying filesystem (see
containers-storage.conf(5)). In that case the program can be manually installed, and
mount_program option can be manually set by the user.
