	RELENG_4, cvsupped within the last 4 hours
	Bugs not evident as of last cvsup around mid-June.

>Description:

	dhclient seems to have two odd bugs:

	1) the broadcast address applied to the interface, if
	   not specified by the DHCP server, is wrong - on this
	   /24 it gets a.b.c.0 instead of a.b.c.255

	2) the "domain" specified by the DHCP server somehow
	   gets "\000" (four characters, NOT a literal null)
           appended to it before dhclient-script uses it to
	   build /etc/resolv.conf.


>How-To-Repeat:

	run dhclient with a DHCP server that doesn't supply
	broadcast address. (Not sure what triggers the "\000"
	feature.)

>Fix:

	Unknown.
