+Bugzilla: N/A
+Upstream-status: queued in NFS git tree (for 3.13/3.14?)
+
+Currently, the client will attempt to use krb5i in the SETCLIENTID call
+even if rpc.gssd isn't running. When that fails, it'll then fall back to
+RPC_AUTH_UNIX. This introduced a delay when mounting if rpc.gssd isn't
+running, and causes warning messages to pop up in the ring buffer.
+
+Check to see if rpc.gssd is running before even attempting to use krb5i
+auth, and just silently skip trying to do so if it isn't. In the event
+that the admin is actually trying to mount with krb5*, it will still
+fail at a later stage of the mount attempt.
