Bug description:
  Description:	Ubuntu 12.04.1 LTS
  Release:	12.04
  Ifenslave-2.6 version: 1.1.0-19ubuntu5

  First of all; I am not 100% sure this bug is in ifenslave-2.6, but
  ifenslave-2.6 is definately affected by the bug in general.

  I have installed a system using PXE and preseed, which automatically
  partitions seperate /, /usr, /var, /tmp and swap partitions. After
  installing ifenslave and configuring it using the configuration
  example in /usr/share/doc/ifenslave-2.6/examples/two_hotplug_ethernet,
  I reboot the server to test if it comes up after booting.

  The result is a bond0 that came up, but eth0 and eth1 haven't joined
  in as slaves.

  In /var/log/upstart/network-interface-bond0.log, I noticed the
  following:

  Waiting for a slave to join bond0 (will timeout after 60s)
  /etc/network/if-pre-up.d/ifenslave: 240: /etc/network/if-pre-up.d/ifenslave: seq: not found
  No slave joined bond0, continuing anyway
  Failed to bring up bond0.

  It seems that seq is not available at the time /etc/network/if-pre-
  up.d/ifenslave is ran. To verify, I added a 'df -h' at the top of the
  script, and rebooted, noticing indeed only my root filesystem is
  mounted when the script runs:

  Filesystem               Size  Used Avail Use% Mounted on
  /dev/mapper/rootvg-root  3.8G  631M  3.0G  18% /
  udev                     5.9G  260K  5.9G   1% /dev
  tmpfs                    2.4G  240K  2.4G   1% /run
  none                     5.0M     0  5.0M   0% /run/lock
  Waiting for a slave to join bond0 (will timeout after 60s)
  /etc/network/if-pre-up.d/ifenslave: 240: /etc/network/if-pre-up.d/ifenslave: seq: not found
  No slave joined bond0, continuing anyway
  Failed to bring up bond0.

  Naturally, after booting is done, all filesystems are available. When
  running ifdown -a; ifup -a when this was the case, the bond actually
  does come up.

  Eventually, I made a quick-fix for myself by copying /usr/bin/seq to
  /bin/seq, which solves the issue.

  Now, I'm quite new to Ubuntu (we are figuring out if we can and want
  to migrate our servers from Debian to Ubuntu), and especially upstart,
  but from what I can see, the networking upstart script only starts on
  'local-filesystems', which I assume is emited only when all
  filesystems are actually mounted (but here is where my knowledge
  pretty much ends).

  If further information is needed, just let me know!
