Brilliant phrasing: "The expected configuration" falls so hard into the
deep black hole of bug number 1 that there is no come back.

I wonder what the people that don't know about /etc/resolv.conf and
resolvconf do.

Title:
  resolvconf incorrectly configures resolv.conf

Status in “resolvconf” package in Ubuntu:
  Invalid

Bug description:
  This has happened a number of times both with some laptops. When they
  get up resolv.conf contains this:

  $ cat /etc/resolv.conf 
  # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
  #     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
  nameserver 127.0.0.1
  search langfeldt.net

  This is nowhere like right and makes it impossible to get name-
  resolution. When I remove resolvconf everything works right. This is
  right:

  $ cat /etc/resolv.conf 
  # Generated by NetworkManager
  domain langfeldt.net
  search langfeldt.net
  nameserver 192.168.1.1

  (except that domain and search should not appear in the same
  resolv.conf file).

  # apt-cache policy resolvconf
