	FreeBSD 4.7-STABLE
>Description:
	I have a machine with a vlan interface created with the
	following rc.conf entries:

	cloned_interfaces="vlan4" 
	ifconfig_vlan4="vlan 4 vlandev fxp0"


	this vlan interface has to do dhcp for it's ip
	address, however I can't do :

	cloned_interfaces="vlan4" 
	ifconfig_vlan4="DCHP"

	because that leaves the vlandev is un-configured.
>How-To-Repeat:
	not aplicable
>Fix:

	don't empty dhcp_interfaces in rc.network line 194
	( dhcp_interfaces="" ) which enables the following setup :
	
	cloned_interfaces="vlan4"
	ifconfig_vlan4="vlan 4 vlandev fxp0"
	dhcp_interfaces="vlan4"

	Which makes sense because you can specify network, ipv6_network
	and gif interfaces in rc.conf as well. This change makes dhcp
	possible on interfaces that need ifconfigging before they
	are dhcp ready. I think that this is a better solution than
	using /etc/start_if.${ifn} scripts because it keeps the config
	in rc.conf where it belongs. I also don't see why the emptying
	of dhcp_interfaces in rc.network is needed.
