That *is* a problem. Indeed NetworkManager has gained support for RDNSS for a long time already, and thus made completely rdnssd redundant if not counter- productive on a system with NetworkManager. But as far as I know, whatever caused this default is not rdnssd itself. > I believe that it should do something saner instead of overwriting. I must disagree. If resolvconf is absent, overwriting is the most sane, or least insane thing to do. There just is not a lot that can be done without mediation for writing the resolver configuration. > It should verify if the file contains the DNS servers it detected > and add them if they are missing.

There are currently no ways to know which entries were inserted by rdnssd (possibly by a previous incantation of it) and which by other tools. Furthermore, I doubt we can safely assume that all resolv.conf tools remove their entries when uninstalled. I think this suggestion is worse than the bug from a reliability perspective. Really, any pair of two tools writing resolv.conf will screw stuff up without resolvconf present and supported by both tools. That problem affects ppp, dhcp- client3, network-manager, wicd, connman, systemd(-networkd) just to name a few. And I don´t dare mention most if not all VPN clients. -- Rémi Denis-Courmont http://www.remlab.net/ -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of "unsubscribe".
