Package: network-manager
Version: 1.6.2-3+deb9u2
Severity: normal

Dear Maintainer,

Bug description:
  I am using raspbian (debian based)
  PRETTY_NAME="Debian GNU/Linux 9 (stretch)"

  trying to switch from dhcp to a static IP. But dns config changes keep
  on failing

  The config files I am using that configure static ip and an dns-server are 

  I would suspect networkmanager would thus:
  * manage the file /etc/resolvconf/run/resolv.conf
  * to read *ONLY* the dns-server

  However, some (probably systemd?) proces also adds
  I suspect because on debian this file (which I did not alter) contains the dns server:

  root@bananas:~# cat /etc/resolvconf/resolv.conf.d/head 

  Anyway, after I configured only 1 dns-server and a reboot the resolv.conf 
file falsely now holds *TWO* dns-severs, and I did not

Here is that file
  root@bananas:~# cat /etc/resolvconf/run/resolv.conf

  I was wondering if this is a bug in networkmanager? Should it not make
  sure resolv.conf reflects its configfiles?
