-# In most Linux versions this can be done using something like the following...

+#   [statd]
+#     name = mycluster

 # /etc/sysconfig/nfs (Red Hat) or /etc/default/nfs-common (Debian):
-#   NFS_HOSTNAME=myhostname
+#   NFS_HOSTNAME=mycluster
 #   STATD_HOSTNAME="${NFS_HOSTNAME} -H /etc/ctdb/statd-callout"
