+.I Seconds
+should be the minimum number of seconds since a client began trying to
+acquire a new lease before the DHCP server will respond to its request.
+The number of seconds is based on what the client reports, and the maximum
+value that the client can report is 255 seconds.   Generally, setting this
+to one will result in the DHCP server not responding to the client's first
+request, but always responding to its second request.

+This can be used
+to set up a secondary DHCP server which never offers an address to a client
+until the primary server has been given a chance to do so.   If the primary
+server is down, the client will bind to the secondary server, but otherwise
+clients should always bind to the primary.   Note that this does not, by
+itself, permit a primary server and a secondary server to share a pool of
+dynamically-allocatable addresses.
