[Bug 916890] Re: "Waiting for network configuration" on every boot

[Jani Uusitalo]

You're right: it's announce-ip and another local script from
/etc/network/if-up.d/ (I'm attaching it here) that both seem to trigger
this if either is present. This other one's sort of like the opposite of
my announce-ip, there to update /etc/hosts with data from hosts
elsewhere on the net my server knows about (that announce themselves
with announce-ip). This combination used to work back with ifupdown
alpha but now with beta causes the wait.

To clarify: with both scripts removed from if-up.d the 60+ second wait
doesn't appear during boot, but with either script in place the wait is
there.

To be sure, I installed the latest ifupdown that's just appeared in the
repos (0.7~beta2ubuntu2) also, and there's no change compared to
0.7~beta2ubuntu1 (wait is there when the scripts are there).

The question now becomes whether I've initially designed the scripts
wrong with regards to how things in if-up.d should work, and it just
happened to work with the alpha, or did something in ifupdown's handling
of if-up.d change between alpha and beta so that things that should work
no longer do.

With my knowledge of things I'd bet on the former, but you can probably
enlighten me on this. My assumption's been that the scripts in if-up.d
are run after network interfaces have been brought up.

Title:
  "Waiting for network configuration" on every boot

Status in “ifupdown” package in Ubuntu:
  Confirmed

Bug description:
  Upgrade from 0.7~alpha5.1ubuntu6 to 0.7~beta2ubuntu1 brought this on:
  on every boot the "Waiting for network configuration" and "Waiting up
  to 60 seconds more for network" messages appear and boot is thus about
  2 minutes slower than before. It also says it's booting without
  network, but the network is in fact there after I log in.

  Downgrading back to 0.7~alpha5.1ubuntu6 makes the wait go away again.

  Reproduced this on three different computers on two different
  networks, both wired and wireless.
