[Bug 1015199] Re: ifup does not work as documented with bonding interfaces

FTR, system did boot to working network interfaces with the above
configuration (including pre-up/sleep lines).  I'm not sure if there
were warnings issued as the default Ubuntu last action on boot is to
clear all boot messages in favour of displaying the login prompt at the
top of the screen :-(  (/var/log/boot.log contains no messages other
than "starting ..." lines.)

FWIW, it seems to me that "ifup bond0" should do the enslaving
immediately of any bond-slave interfaces that actually already exist;
leaving (and maybe waiting for at least one of ) any others that don't
currently exist to appear and auto-config later on.  That should work
both with races on discover on first boot, and through ifdown/ifup bond0
cycle later on (when the slave interfaces most likely still exist, even
though they've been disabled by the ifdown bond0).

Title:
  ifup does not work as documented with bonding interfaces

Status in ifenslave-2.6 package in Ubuntu:
  Fix Released

Bug description:
  The file /usr/share/doc/ifenslave-2.6/README.Debian.gz states:

  "Using ifup on a master interface will call ifup for all slaves that are
  flagged with allow-bondX. (bondX being replaced by the master interface
  name). This will allow for extra setup for special slave interfaces."

  However I'm using this /etc/network/interfaces file:

  # The bound interface 
  auto eth3
  allow-bond0 eth3
  iface eth3 inet manual
    bond-master bond0
    bond-primary eth3 eth4 eth5

  auto eth4
  allow-bond0 eth4
  iface eth4 inet manual
    bond-master bond0
    bond-primary eth3 eth4 eth5

  auto eth5
  allow-bond0 eth5
  iface eth5 inet manual
    bond-master bond0
    bond-primary eth3 eth4 eth5

  auto bond0 
  iface bond0 inet static
    address 10.1.1.125
    network 10.1.0.0
    netmask 255.255.0.0
    broadcast 10.1.255.255
    bond-mode balance-rr
    bond-slaves eth3 eth4 eth5
    bond-miimon 100
    bond-downdelay 200
    bond-updelay 200

  and issuing the 'ifup bond0' command I get:

  root@:~# ifup bond0
  Waiting for a slave to join bond0 (will timeout after 60s)
  No slave joined bond0, continuing anyway
  ssh stop/waiting
  ssh start/running, process 9610

  As you can see no slave interface has been started.
