- * Here's the scoop concerning the user[.:]group feature:
+/* inetd rules for passing file descriptors to children
+ * (http://www.freebsd.org/cgi/man.cgi?query=inetd):
+ *
+ * The wait/nowait entry specifies whether the server that is invoked by
+ * inetd will take over the socket associated with the service access point,
+ * and thus whether inetd should wait for the server to exit before listen-
+ * ing for new service requests. Datagram servers must use "wait", as
+ * they are always invoked with the original datagram socket bound to the
+ * specified service address. These servers must read at least one datagram
+ * from the socket before exiting. If a datagram server connects to its
+ * peer, freeing the socket so inetd can receive further messages on the
+ * socket, it is said to be a "multi-threaded" server; it should read one
+ * datagram from the socket and create a new socket connected to the peer.
+ * It should fork, and the parent should then exit to allow inetd to check
+ * for new service requests to spawn new servers. Datagram servers which
+ * process all incoming datagrams on a socket and eventually time out are
+ * said to be "single-threaded". The comsat(8), (biff(1)) and talkd(8)
+ * utilities are both examples of the latter type of datagram server. The
+ * tftpd(8) utility is an example of a multi-threaded datagram server.
+ *
+ * Servers using stream sockets generally are multi-threaded and use the
+ * "nowait" entry. Connection requests for these services are accepted by
+ * inetd, and the server is given only the newly-accepted socket connected
+ * to a client of the service. Most stream-based services operate in this
+ * manner. Stream-based servers that use "wait" are started with the lis-
+ * tening service socket, and must accept at least one connection request
+ * before exiting. Such a server would normally accept and process incoming
+ * connection requests until a timeout.
