resolv.conf produces errors when postfix main.cfg is missing (regression of #530323)

[Paul Boven]

This seems to be a regression of #530323 on 12.04 LTS:

# ifup eth0
/etc/resolvconf/update-libc.d/postfix: 7: /etc/resolvconf-update-libc.d/postfix: /usr/sbin/postconf: not found
cp: '/etc/resolv.conf' and '/etc/resolv.conf' are the same file
run-parts: /etc/resolvconf/update-libc.d/postfix exited with return code 1
run-parts: /etc/resolvconf/update.d/libc exited with return code 1
run-parts: /etc/network/if-up.d/000resolvconf exited with return code 1

Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately, we cannot work on this bug because your description didn't include enough information. You may find it helpful to read "How to report bugs effectively" http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem.

We have instructions on debugging some types of problems at http://wiki.ubuntu.com/DebuggingProcedures

At a minimum, we need:
1. the specific steps or actions you took that caused you to encounter the problem,
2. the behavior you expected, and
3. the behavior you actually encountered (in as much detail as possible).
Thanks!
