[Bug 885278] [NEW] /etc/init/network-interface.conf should specify INTERFACE= rather than IFACE=

[James Hunt]

Public bug reported:

The Upstart job /etc/init/network-interface.conf special-cases the 'lo'
network interface by manually emitting a net-device-up event with
'IFACE=lo'. This is wrong and is confusing users who are specifying
'start on net-device-up INTERFACE=eth0' for example. The result here is
that users jobs start too early (when the *first* network interface
comes up, rather than when *their* interface comes up!!)

It should actually specify INTERFACE=lo since that is the name of the
variable set in the udev message. To see this, search for '=<interface>'
in /var/log/udev (for example search for '=eth0').

Since a number of jobs now specify 'start on net-device-up IFACE=lo', I
suggest we modify /etc/init/network-interface.conf to do the following
for interface 'lo':

  initctl emit -n net-device-up IFACE=lo INTERFACE=lo LOGICAL=lo
ADDRFAM=inet METHOD=loopback

The correct fix would be to change IFACE to INTERFACE *and* change all
the jobs that use IFACE, but pragmatically it is easier to add
'INTERFACE='.

I'll update the upstart cookbook on this topic.
