>Description:
	ISC changed the behavior of the DHCP server between 3.0.2 and
	3.0.3 (imported by drochner@ on 11 August 2005). Previously,
	the behavior was as described in dhcpd.conf.5:

	If no next-server parameter applies to a given client, the DHCP
	server's IP address is used.

	Since the change, from src/dist/dhcp/RELNOTES:

	The siaddr field is now left zeroed unless next-server is
	configured.

	However, ISC left the now-incorrect sentence in dhcpd.conf.5.
	(It has been removed in their 3.0.4 release.)

	Reported by Wojciech Puchar and Patrick Welche on current-users,
	20 and 22 September 2005.

>How-To-Repeat:
	Clear by observation.
>Fix:
	Remove the incorrect sentence (longer term, import 3.0.4).

 Note: As Seen On current-users, the incantation:

   next-server = option dhcp-server-identifier;

 is a way to preserve the previous behavior that supplied the server's
 address without a need to hardcode it in the configuration file.
