Description of problem: The ceph-nfs container runs nfs-ganesha to support the CephFS FSAL and provide NFS shared file systems through openstack-manila. It uses the host's dbus socket and accepts commands over this socket from the CephFS via NFS driver in openstack-manila. This container does not need to be run as a privileged process. Please see a discussion here https://github.com/ceph/ceph-ansible/blob/f49090df7ef82419c69dfd7a22250a79c17de42f/roles/ceph-nfs/templates/ceph-nfs.service.j2#L21
