+The complete set of CITI nfs-utils patches rolled into one patch.
+
+Changes since 1.0.8-rc4-CITI_NFS4_ALL-3:
+
+ * Update to the final nfs-utils-1.0.8
+
+ * Check for problems with the gssapi library in gssd and svcgssd
+ early on, so we can give a good error message and bail out.
+
+ * Add temporary patch to svcgssd to use default values when the
+ mapping of the gss principal to uid/gid fails. This may need
+ to somehow coordinate with the anonuid/anongid values for the
+ export.
