+* `--device=/dev/fuse`: Pass in host FUSE device.
+* `--cap-add=SYS_ADMIN`: Give proper permissions to mount.
+* `-v /mnt/mergerfs:/mnt/mergerfs:z,shared`: `z` and `shared` will
+  allow the mount to be shared between the container and host and
+  therefore other containers.

+Not possible? `:shared` is not rejected but won't work the same with
+rootless. Podman doesn't allow the creation of pods with shared mount
+namespace in rootless mode.
