Title:
  network with bonding does not start on ubuntu with separate /var
  partition

Status in “ifenslave-2.6” package in Ubuntu:
  New

Bug description:
  I believe there are benefits of having a separate /var partition,
  unfortunately having bonding-configured network start up with the OS
  is not one of them. Or atleast not in a timely fashion.

  I've done this experiment on two identical hp bl460c g1 blades, only
  difference was the partitioning scheme.

  Here's the identical /etc/network/interfaces

  # The loopback network interface
  auto lo
  iface lo inet loopback

  # The badass network interface
  auto bond0
  iface bond0 inet dhcp
  	bond-slaves none
  	bond-mode 1
  	bond-miimon 100

  # The primary network interface
  auto eth0
  iface eth0 inet manual
  	bond-master bond0
  	bond-primary eth0 eth1

  # The secondary network interface
  auto eth1
  iface eth1 inet manual
  	bond-master bond0
  	bond-primary eth0 eth1
