Installing bind9 and resolvconf at the same time fails

Looking at the logs there seem to be severa

 * Starting domain name service... bind9  resolvconf: Error: /etc/resolv.conf must be a symlink

invoke-rc.d: initscript bind9, action "start" failed.

^Cdpkg: erro processando bind9 (--configure):

 sub-processo script post-installation instalado foi morto por sinal (Interrupção)

This is a race between resolvconf and bind9 installs.
"sudo apt-get install bind9 resolvconf" results in:
bind9 unpack
resolvconf unpack
bind9 configure > fails to start with "resolvconf: Error: /etc/resolv.conf must be a symlink"

bind9 starts up while the link isn't set up yet (will be done in resolvconf configure)

Doing the install in two separate runs works:
sudo apt-get install resolvconf
sudo apt-get install bind9

resolvconf needs to not fail when invoked by bind9 during bind9's configure while resolvconf is unpacked but not configured.

 Is this causing Bug #510497

This is Debian bug #551999 which was fixed in Debian resolvconf release 1.49. The current version of resolvconf in Debian is 1.58.

A new Ubuntu resolvconf package has been prepared by the Debian maintainers.

I ask you to test this new package before we upload it to the Ubuntu repos.

Please install the resolvconf package from ppa:jdthood/resolvconf (https://launchpad.net/~jdthood/+archive/resolvconf) and let me know whether or not you have any problems with it.

This bug was fixed in the package resolvconf - 1.63ubuntu1

---------------
resolvconf (1.63ubuntu1) precise; urgency=low

  [ Thomas Hood ]
  * Debian fixed bugs (LP: #797339, #871058, #471975, #378844, #894417)
  * Differences from Debian:
    - /sbin/resolvconf:
      + Exit if /etc/resolv.conf is not a symlink
    - debian/rules:
      + Install upstart script rather than initscript (LP: #366967, #750423)
    - debian/{pre,post}inst
      + Migrate (to /run) from /var/run, not from /lib/init/rw.
      + [0706f28] Remove old Sys V init scripts and symlinks
  * Thanks to Sander van Grieken for his assistance with this release.

resolvconf (1.63) unstable; urgency=low

  [ Thomas Hood ]
  * [a83fce3] Depend on a later version of the initscripts package
  * [cfc8349] Use variable instead of hard-coded path for old run dir
    in maintainer scripts, to help shrink the Ubuntu diff.
  * [9921902] Update and improve resolvconf(8)
  * [719dc9b] Run update on boot (Closes: #651801, #651827)

resolvconf (1.62) unstable; urgency=low

  [ Thomas Hood ]
  * [0352a85] postrm: On removal restore original resolv.conf if current
    (dynamic) resolv.conf has no content. (Closes: #644956)
    Thanks to Josep Lladonosa Capell.
  * [7cdfa73] Move logic details from initscript to /sbin/resolvconf;
    for this purpose add new options to /sbin/resolvconf:
    --enable-updates, --disable-updates, --updates-are-enabled,
    --create-runtime-directories.
  * [7cdfa73] Eliminate "-i" option supplied to update scripts and
    the code in /etc/resolvconf/update.d/libc that made use of this.
