+ * NSM for Linux.
+ *
+ * Callback information and NSM state is stored in files, usually
+ * under /var/lib/nfs. A database of information contained in local
+ * files stores NLM callback data and what remote peers to notify of
+ * reboots.
+ *
+ * For each monitored remote peer, a text file is created under the
+ * directory specified by NSM_MONITOR_DIR. The name of the file
+ * is a valid DNS hostname. The hostname string must be a valid
+ * ASCII DNS name, and must not contain slash characters, white space,
+ * or '\0' (ie. anything that might have some special meaning in a
+ * path name).
+ *
+ * The contents of each file include seven blank-separated fields of
+ * text, finished with '\n'. The first field contains the network
+ * address of the NLM service to call back. The current implementation
+ * supports using only IPv4 addresses, so the only contents of this
+ * field are a network order IPv4 address expressed in 8 hexadecimal
+ * characters.
+ *
+ * The next four fields are text strings of hexadecimal characters,
+ * representing:
+ *
+ * 2. A 4 byte RPC program number of the NLM service to call back
+ * 3. A 4 byte RPC version number of the NLM service to call back
+ * 4. A 4 byte RPC procedure number of the NLM service to call back
+ * 5. A 16 byte opaque cookie that the NLM service uses to identify
+ * the monitored host
+ *
+ * The sixth field is the monitored host's mon_name, passed to statd
+ * via an SM_MON request.
+ *
+ * The seventh field is the my_name for this peer, which is the
+ * hostname of the local NLM (currently on Linux, the result of
+ * `uname -n`). This can be used as the source address/hostname
+ * when sending SM_NOTIFY requests.
+ *
+ * The NSM protocol does not limit the contents of these strings
+ * in any way except that they must fit into 1024 bytes. Our
+ * implementation requires that these strings not contain
+ * white space or '\0'.
