[ale] DHCPD conf file

[cfowler]

Is there a way I can tell dhcpd3 to ignore a certain mac?  I use my eth0
on my laptop as a router for my VOIP phone.  I use a crossover cable
between my phone and it.  When I turn the phone off and pack on my
lapopt detects a CAT-5 connection and runs dhclient.  Bamn it gets an IP
from its own server and then everything is broken.  It is no longer the
gateway and has nicely replaced /etc/resolv.conf.  I can turn off dhcp
in the configuration but I also use this interface to connect to
networks.  I want to simply tell dhcpd.conf is possible that if it
receives a DHCP request from this interface to ignore it.
