dhclient should send host name by default

[Jerome Haltom]

dhclient contains the ability to configure send-host in /etc/dhcp3/dhclient.conf. This results in the text string being sent to the DHCP server when requesting an address. Windows boxes, by default, send the system host name + any configured domain name along with this request. Additionally, in Windows networks (Active Directory) DHCP is usually configured to create a DNS A record in response to a host requesting an address.

dhclient should, by default, send essentially $(hostname --fqdn) to the DHCP server by default.

This bug is part of the push for the network-authentication spec.

Scratch the hostname --fqdn part. The domain name has to be set on the system in some place. Suggestions welcome.

FYI: AFAIK, on windows, the host sends its own FQDN with the DHCP request. But WIndows hosts usually have a FQDN linked to the AD network. A domainname sometimes is configured through a DHCP option.
