Turns out this is something directly in klibc in the case of xenial: since xenial is not yet using isc-dhcp for IPv4 DHCP, since that was deemed too intrusive a change for xenial.

In other words, while DHCPv6 is done via isc-dhcp, DHCPv4 is done via ipconfig (klibc); which will need to be fixed to follow the same logic as isc-dhcp w.r.t DOMAINSEARCH handling.

In general, I think having DOMAINSEARCH contain the existing DNS domain if it's not otherwise set by the DHCP server is sensible.

I set the xenial task to High since it might actually impact a lot of people, but it's not as high for artful/zesty given that isc-dhcp is used instead (still ought to land there since people might want to use ipconfig on their own, etc.).
