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

[Dimitri John Ledkov]

Correct that there is a bug with debootstrap above, if both this new
systemd & resolvconf are being bootstrapped together. (as both
src:systemd and src:resolvconf try to setup /etc/resolv.conf symlink)

Dropping resolvconf from important should resolve this.

The ExecStartPre change should then be dropped.

Title:
  resolv.conf symlink is broken after clean debootstrap

Status in systemd package in Ubuntu:
  In Progress

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.
