In order to enable authentication using LDAP over TLS in Jellyfin, we
need to expose the CA certificate that issues the LDAP server
certificates to the container.
Even with `Network=host`, Podman tries to write to
`/etc/containers/network` for some reason. Fortunately, it doesn't
actually need to, so we can trick it into working by mounting an empty
*tmpfs* filesystem there.
Jellyfin is a multimedia library manager. Clients can browse and stream
music, movies, and TV shows from the server and play them locally
(including in the browser).
