-Run the @command{lshd} program from @var{lsh} to listen on port @var{port-number}.
-@var{host-key} must designate a file containing the host key, and readable
-only by root.
-
-When @var{daemonic?} is true, @command{lshd} will detach from the
-controlling terminal and log its output to syslogd, unless one sets
-@var{syslog-output?} to false.  Obviously, it also makes lsh-service
-depend on existence of syslogd service.  When @var{pid-file?} is true,
-@command{lshd} writes its PID to the file called @var{pid-file}.
-
-When @var{initialize?} is true, automatically create the seed and host key
-upon service activation if they do not exist yet.  This may take long and
-require interaction.
-
-When @var{initialize?} is false, it is up to the user to initialize the
-randomness generator (@pxref{lsh-make-seed,,, lsh, LSH Manual}), and to create
-a key pair with the private key stored in file @var{host-key} (@pxref{lshd
-basics,,, lsh, LSH Manual}).
-
-When @var{interfaces} is empty, lshd listens for connections on all the
-network interfaces; otherwise, @var{interfaces} must be a list of host names
-or addresses.
-
-@var{allow-empty-passwords?} specifies whether to accept log-ins with empty
-passwords, and @var{root-login?} specifies whether to accept log-ins as
-root.

+Data type representing the configuration of @command{lshd}.

+@table @asis
+@item @code{lsh} (default: @code{lsh}) (type: file-like)
+The package object of the GNU@tie{}lsh secure shell (SSH) daemon.
+
+@item @code{daemonic?} (default: @code{#t}) (type: boolean)
+Whether to detach from the controlling terminal.
+
+@item @code{host-key} (default: @code{"/etc/lsh/host-key"}) (type: string)
+File containing the @dfn{host key}.  This file must be readable by
+root only.
+
+@item @code{interfaces} (default: @code{()}) (type: list)
+List of host names or addresses that @command{lshd} will listen on.
+If empty, @command{lshd} listens for connections on all the network
+interfaces.

+Port to listen on.
+
+@item @code{allow-empty-passwords?} (default: @code{#f}) (type: boolean)
+Whether to accept log-ins with empty passwords.

+@item @code{root-login?} (default: @code{#f}) (type: boolean)
+Whether to accept log-ins as root.
+
+@item @code{syslog-output?} (default: @code{#t}) (type: boolean)
+Whether to log @command{lshd} standard output to syslogd.
+This will make the service depend on the existence of a syslogd service.
