[Bug 1189521] [NEW] ifdown thinks interface is not up

Mon Jun 10 15:39:23 UTC 2013

Public bug reported:

on 13.04 image on azure
$ cat /etc/cloud/build.info 
build_name: server
serial: 20130601
$ lsb_release -c
Codename:       raring

A couple things wrong/weird:
 * ifdown says the interface isn't configured (but it clearly is)
 * something ran 'start networking' rather than letting the networking come up on its own as a result of configuration in /etc/network/interfaces and network-interface.conf
 * dhclient is dead (seems to not like the lease response?)
 * static-networking-up has (probably) not been emitted as it would be emitted based on eth0 coming up correctly (through /etc/network/if-up.d/upstart)

I'm moderately surprised that there is not other fallout of this. It
seems to work, but I'm sure something is broken by the odd state.
