[Bug 885596] Re: "Waiting up to 60 more seconds for network configuration" at boot

To be honest I don't remember any manual modification sooner or later in 2/2010, but of course I can't be sure. 
I don't remember any networking issue, so there shouldn't be any reason for modifying this file.
Is diff telling us something? I see a "-n" near "initctl emit".
Thanks

Title:
  "Waiting up to 60 more seconds for network configuration" at boot

Status in “ifupdown” package in Ubuntu:
  Incomplete

Bug description:
  Ubuntu 11.10 32bit on Virtualbox and Win7 x64.
  I get a "Waiting up to 60 seconds for network configuration" at boot, which causes the boot to be delayed by some minutes.
  It's not a duplicate of bug #881079

  ------

  /etc/network/interfaces:
  # This file describes the network interfaces available on your system
  # and how to activate them. For more information, see interfaces(5).

  # The loopback network interface
  auto lo
  iface lo inet loopback

  # The primary network interface
  auto eth0
  iface eth0 inet dhcp

  Here's an extract of what Steve Langasek found to be "weird" in the
  kernel log (verbose mode) attached here:
