network manager does not support DNS caches

[Hadmut Danisch]

Binary package hint: network-manager

Hi,

this is related to bug #324233, but not the same.

If you use a dns cache (such as pdnsd) together with dhcp, there's a special requirement: You have to fetch the nameservers from the dhcp server, but pass them to some script to reconfigure the dns cache without modifying /etc/resolv.conf.

networkmanager seems to be unable to do that. It can do it in two ways: Either fetch the nameservers from the dhcp server and replace /etc/resolv.conf, or take a preconfigured setting and don't pass the dhcp server's nameserver. That's odd. This also violates the resolvconf strategy (see #324233).

After all, networkmanager is still not well integrated into the ubuntu/debian environment.

regards
Hadmut
