No free leases

[Marcos Iuato]

Hi shishir,

We develop an solution for remote boot, we use dhcp to tell to the 
terminal where is the nfs server to use as rootfs.

The network that are configured is:

Host running dhcp server:
	eth0: connected to internet - 172.16.36.6
	eth1: terminals from 192.168.11.1 to 192.168.11.144
	eth2: terminals from 192.168.21.1 to 192.168.21.144

NFS server #1
	eth1: terminals from 192.168.11.1 to 192.168.11.144

NFS server #2
	eth1: terminals from 192.168.21.1 to 192.168.21.144
