+@deffn {Scheme Procedure} dhcpd-service-type
+This type defines a service that runs a DHCP daemon.  To create a
+service of this type, you must supply a @code{<dhcpd-configuration>}.
+For example:
+
+@example
+(service dhcpd-service-type
+         (dhcpd-configuration
+          (config-file (local-file "my-dhcpd.conf"))
+          (interfaces '("enp0s25"))))

+@deftp {Data Type} dhcpd-configuration
+@table @asis
+@item @code{package} (default: @code{isc-dhcp})
+The package that provides the DHCP daemon.  This package is expected to
+provide the daemon at @file{sbin/dhcpd} relative to its output
+directory.  The default package is the
+@uref{http://www.isc.org/products/DHCP, ISC's DHCP server}.
+@item @code{config-file} (default: @code{#f})
+The configuration file to use.  This is required.  It will be passed to
+@code{dhcpd} via its @code{-cf} option.  This may be any ``file-like''
+object (@pxref{G-Expressions, file-like objects}).  See @code{man
+dhcpd.conf} for details on the configuration file syntax.
+@item @code{version} (default: @code{"4"})
+The DHCP version to use.  The ISC DHCP server supports the values ``4'',
+``6'', and ``4o6''.  These correspond to the @code{dhcpd} program
+options @code{-4}, @code{-6}, and @code{-4o6}.  See @code{man dhcpd} for
+details.
+@item @code{run-directory} (default: @code{"/run/dhcpd"})
+The run directory to use.  At service activation time, this directory
+will be created if it does not exist.
+@item @code{pid-file} (default: @code{"/run/dhcpd/dhcpd.pid"})
+The PID file to use.  This corresponds to the @code{-pf} option of
+@code{dhcpd}.  See @code{man dhcpd} for details.
+@item @code{interfaces} (default: @code{'()})
+The names of the network interfaces on which dhcpd should listen for
+broadcasts.  If this list is not empty, then its elements (which must be
+strings) will be appended to the @code{dhcpd} invocation when starting
+the daemon.  It may not be necessary to explicitly specify any
+interfaces here; see @code{man dhcpd} for details.
