[Bug 1713149] Re: resolv.conf symlink is broken after clean debootstrap

[Steve Langasek]

This may have been fixed just now by demoting resolvconf from important
to extra.  If the next image build is still broken after this change,
please shout.

Ideally the debootstrap would have worked at all points without archive
override changes, but having missed that, we should just get resolvconf
out of the way.

Title:
  resolv.conf symlink is broken after clean debootstrap

Status in systemd package in Ubuntu:
  Incomplete

Bug description:
  Reproducer:
   - debootstrap artful artful

  Expected:
   - "chroot artful cat /etc/resolv.conf" doesn't fail.
   - /etc/resolv.conf is a symlink to something valid in /run

  Actual:
   - "chroot artful cat /etc/resolv.conf" gets you "No such file or directory"
   - /etc/resolv.conf is a symlink to "../run/resolvconf/resolv.conf"
   - "../run/resolvconf/resolv.conf" is a symlink to "../run/systemd/resolve/stub-resolv.conf" which is an invalid symlink as that points to /run/run/systemd/resolve/stub-resolv.conf" rather than "/run/systemd/resolve/stub-resolv.conf"

  This causes all LXC image creation to fail, causing autopkgtest to
  fail (as noticed by the kernel team) and has been causing all images
  to fail building on the upstream build system for the past two days.
