+The @code{(gnu services rpcbind)} module provides the following service.
+
address@hidden {Scheme Procedure} rpcbind-service [#:rpcbind rpcbind] @
+       [#:warm-start? #t]
+Return a service that runs @command{rpcbind}, a server which converts RPC
+program numbers to universal addresses.
+
+Optionally, the package where the daemon is to be found, @var{rpcbind}, may be
+specified.
+If @var{warm-start?} is true (the default), then it will read a state file on
+startup and thus reload state information saved saved by the previous instance.
