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

[Steve Langasek]

It is documented in the 12.04 release notes, and the installer has been
adding this line automatically for years whenever static networking is
selected at install time.

It's probably reasonable to also have it documented in interfaces(5), or
at least a link provided to the resolvconf manpage, although I think
it's unlikely that users will look there first when trying to debug why
their nameserver entries have disappeared.  That manpage belongs to the
ifupdown package, so reassigning.

** Package changed: resolvconf (Ubuntu) => ifupdown (Ubuntu)

** Changed in: ifupdown (Ubuntu)
   Importance: Undecided => Wishlist

** Changed in: ifupdown (Ubuntu)
       Status: New => Triaged

  /etc/network/interfaces new requirement for dns-nameservers line is

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.
