[Pkg-utopia-maintainers] Bug#465158: network-manager: Please add support for domain-search

[Andrew Pollock]

Package: network-manager
Version: 0.6.5-5
Severity: wishlist

Hi,

I'd try to provide a patch, but my C-fu is very, very weak...

ISC DHCP 3.1 provides support for the domain-search option. This is the
correct way for a DHCP server to provide a domain search list. Wedging
multiple domains into the domain-name option is a horrible hack.

It seems, however, that that is what NetworkManager expects, and so how
it generates an /etc/resolv.conf. This behaviour should be changed in
light of dhclient 3.1, and should do something like this:

if the domain-search option is present in the data received via DHCP,
use it in favour of the domain-name option for setting the search
directive in /etc/resolv.conf

if the domain-name option is present in the data received via DHCP, use
it to set the domain directive in /etc/resolv.conf

if only the domain-name option is present in the data received via DHCP
(and domain-search is not), for backwards compatibility, set the search
directive in /etc/resolv.conf

It appears, from my testing, that NetworkManager interacts with
resolvconf, so the above only applies when resolvconf is not installed.
I've already filed #460609 to have resolvconf update its behaviour.

This bug is important for consistent treatment of /etc/resolv.conf when
DHCP and the domain-search option is in use.

regards

Andrew
