[Bug 1043335] Re: /etc/network/interfaces new requirement for dns-nameservers line is not well documented

[Launchpad Bug Tracker]

This bug was fixed in the package ifupdown - 0.7.2ubuntu1

---------------
ifupdown (0.7.2ubuntu1) quantal; urgency=low

  * Merge ifupdown 0.7.2 from Debian. Remaining changes:
    - If the /etc/NetworkManager/NetworkManager.conf file is present
      but doesn't have the "ifupdown:managed" the previous upload instructed
      the iniparser to return -1, which evaluates to TRUE. We instead instruct
      it to return 0, as we shouldn't prevent ifupdown from managing the
      interfaces in that case, as NM won't either. (LP: #281984)
    - debian/postinst: If the loopback interface is missing from the config
      in /etc/network/interfaces, add it on upgrade.
    - Add jobs and hooks for upstart.
  * Remove /etc/default/networking as the upstart job doesn't use it and
    can't really use it without some significant changes (support exclusion
    lists in all the upstart jobs).
  * Add resolvconf (8) to SEE ALSO section of the interfaces manpage.
    (LP: #1043335)

ifupdown (0.7.2) unstable; urgency=low

  * Don't install /etc/default/networking as executable (Closes: #679623).
  * Declare Breaks on dhcp-client (<< 3.0) instead of Conflicts.
  * Implement --no-scripts option (LP: #258782).
  * Calculate the length of a string properly (Closes: #681431).
  * When bringing hotplug interfaces up, strip VLAN and alias identifiers out
    (Closes: #680042).
  * LSB headers: depend on urandom.
  * Recognize vlan+alias combination and filter aliases out (Closes: #679672).
  * Work-around ip(8) understanding of 0NNN as octal numbers (Closes: #684698).

Title:
  /etc/network/interfaces new requirement for dns-nameservers line is
  not well documented

Status in “ifupdown” package in Ubuntu:
  Fix Released

Bug description:
  On one machine I have a static (LAN) IP address configured manually in
  /etc/network/interfaces, and I have not had to modify that file for
  several years.  Immediately after upgrading to precise, the machine
  had no DNS, and I eventually discovered that I needed to add a dns-
  nameservers line to the "iface eth0 inet static" stanza.  This is not
  documented in "man interfaces" and the fix was hard to find.  I think
  it should be better documented, and the upgrade process should
  probably suggest it.
