You surely do.  'auto' is a directive to ifupdown to try to start the
interface automatically at boot.  This clearly will always fail according to
your description, so your /etc/network/interfaces is broken and should be
fixed.

You are wrong.  The network can take more than a minute to be configured in
some legitimate circumstances, and it's important that we be as safe as
possible in our failsafe.  Your bug is that you have a misconfigured system
that is causing you to *hit* the failsafe.  A properly configured system
should never hit the timeout.

Bug description:
  SRU justification: any delays in running the rc-sysinit script cause a
  spurious message to appear on the plymouth boot splash saying that the
  boot is waiting for the network to become available when it really
  isn't.  This is confusing and misleading to users.

  At bootup, while displaying the Ubutu logo, it says waiting for
  network configuration. Then it says: "Waiting up to 60 more seconds
  for network configuration", but seems to be stuck until enter key is
  pressed. Out of the syslog file it seems like it tries to start the
  wireless network already at bootup, but fails since the key to the
  network is only available in my user account after logging in.
