When using NFS-over-TLS, an NFS client can optionally provide an X.509 certificate to the server during the TLS handshake. For some situations, such as different NFS servers or different certificates being mapped to different user credentials on the NFS server, there may be a need for different mounts to provide different certificates. This new mount option called "tlscertname" may be used to specify a non-default certificate be provided. This alernate certificate will be stored in /etc/rpc.tlsclntd in a file with a name based on what is provided by this mount option.
