[Bug 1279760] Re: Take into account the debotstrapped environment

[Thomas Hood]

The creation of the symbolic link /etc/resolvconf/resolv.conf.d/tail ->
original, controlled by a debconf question, was introduced in Debian
(where resolvconf is only an optional package, not included in the base
install) in order to minimize the deleterious effects of resolvconf
being installed on a running system whose maintainer isn't yet sure how
to configure resolvconf. The symlink ensures that needed nameserver
addresses are included in resolv.conf until such time as the maintainer
adds those addresses to /etc/network/interfaces (and deletes the
tail->original symlink).

Resolvconf has been part of the base Ubuntu system since 12.04 and so I
would say that as of Ubuntu 14.04 the utility value of this feature is
zero. So long as the feature hasn't been removed from Ubuntu resolvconf,
the default answer to link-tail-to-original should be false. I would
also be in favor of no longer asking the debconf question.

** Summary changed:

- Take into account the debotstrapped environment
+ Resolvconf creates /etc/resolvconf/resolv.conf.d/tail->original symlink in debootstrap environment

Title:
  Resolvconf creates /etc/resolvconf/resolv.conf.d/tail->original
  symlink in debootstrap environment

Status in “resolvconf” package in Ubuntu:
  Confirmed

Bug description:
  When installing resolvconf inside the debootstrapped system it will
  create /etc/resolv.conf.d/original with the DNS server addresses
  available on the host system. This will add the unwanted DNS server
  addresses to the deboostrapped system.

  Resolution: don't inherit the DNS servers from the host system when
  installing resolvconf inside the deboostrapped chroot.
