ARGH!!!!! Every release causes new problems >:(

If you have:
linux DHCP server on the network with options:
option domain-name "xyz.com";
option domain-name-servers,;

In Ubuntu 10.x it works fine and pulls the DHCP client pulls the DNS
servers from the DHCP fine.

Ubuntu 12.x - It's broken.
Trying to fix with: adding to /etc/network/interfaces 
dns-search xyz.com
FAIL. Because you have iface eth0 inet dhcp that option isn't read

Try and configure with Network Manager from commandline because your running a server. 
NOPE, network manager doesn't run from CLI commandline only GUI

Can't manually specify the DNS server in /etc/resolv.conf because it's
always getting overwritten.

What's the best option here? I think this might be a bug. Only option I
haven't tried is using the head file from this description:

Resolvconf has a /etc/resolvconf/resolv.conf.d/ directory that can contain “base”, “head”, “original” and “tail” files. All in resolv.conf format.
base: Used when no other data can be found
head: Used for the header of resolv.conf, can be used to ensure a DNS server is always the first one in the list
original: Just a backup of your resolv.conf at the time of resolvconf installation
tail: Any entry in tail is appended at the end of the resulting resolv.conf. In some cases, upgrading from a previous Ubuntu release, will make tail a symlink to original (when we think you manually modified resolv.conf in the past)
