There was a problem hiding this comment.
Maybe improve the error here - errors.Wrapf(err, "detected that systemd-resolved is in use, but could no locate real resolv.conf") or similar

When 127.0.0.53 is the only nameserver in /etc/resolv.conf assume systemd-resolved is used. This is better because /etc/resolv.conf does not have to be symlinked to /run/systemd/resolve/stub-resolv.conf in order to use systemd-resolved.
