[Pkg-utopia-maintainers] Bug#1031539: network-manager: NM since 1.42.0-1 overwrites pre-existing dns-search entries

[Christoph Anton Mitterer]

Package: network-manager
Version: 1.42.0-1
Severity: normal

Hey.

Just wanted to file this as a bug against ifupdown, but while writing I found out
that actually the upgrade from 1.40.10-1 to 1.42.0-1 causes this:

Ssince around the 10th of Feburary (and I've updated NM on the 11th) my dns-search
doesn't get added to resolvconf anymore.

Since years I have in /etc/network/interfaces:
   iface lo inet loopback
           dns-search      scientia.org

And while I also keep eth/wlan config in it, it's not enabled per default but
NetworkManager is used for that (because of the GUI stuff - talking about a laptop
here). So I have:
   allow-auto      lo
   #allow-hotplug  eth0 wlan0

So ifupdown does basically nothing, except for being there in case NM should have
troubles ... and setting my personal dns-search.
I also use the resolvconf package.

My DHCP sends me an additional fritz.box for the dns-search, which I fail to block ^^
But despite all this, for many years, my own dns-search was always added, too.
Now only the fritz.box remains.



It seems, that since 1.42.0-1 NM no longer just appends its own dns-search domains
(i.e. fritz.box) but also clears out any that are already there.
Downgrading "fixes" that.


Though it's of course arguable, whether this behaviour is actually proper or not.


Anyway... you guys know probably better if that's a desired change or some bug.
If the former, it would perhaps be nice if a NEWS.Debian entry could be added?


Thanks,
Chris.
