+    Introduce a PacemakerTLSPriorities parameter (which will set the PCMK_tls_priorities
+    config option in /etc/sysconfig/pacemaker and the PCMK_tls_priorities variable
+    inside the bundle. This, when set, allows an operator to specify what kind of
+    GNUTLS ciphers are desired for the pacemaker control port.
