[ale] DHCPD conf file

[cfowler]

Not the problem.

The main problem is that if the eth0 connection drops and comes back up
then Ubuntu will run dhclient on that interface.  Dhcpd sees this and
responds.

I think that telling dhcpd to ignore will not work because dhclient will
configure the address as a 169.......  It may be best to just feed
dhclient the correct info.
