upstart event static-network-up emited to early

[john]

My understanding of static-network-up is that it should be emited after all devices have successfully come up however it seems like it is been emited too early

stat -c '%n: %z' /run/network/*
/run/network/ifstate: 2015-01-21 01:51:58.301433828 +0000
/run/network/ifup.eth0: 2015-01-21 01:51:58.277433829 +0000
/run/network/ifup.lo: 2015-01-21 01:51:56.749433883 +0000
/run/network/static-network-up-emitted: 2015-01-21 01:51:56.881433878 +0000

As you can see in the above /run/network/ifup.eth0 was updated after /run/network/static-network-up-emitted

I have checked a few systems and this only seems to effect systems with ipv6 configuration.

Thanks for the bug report john!

This makes perfect sense to me. The original was written assuming eth0 would only have one /e/n/i section, but in the file above, it has two.

I think the answer is to include the address family, so eth0.inet and eth0.inet6 should be two different interfaces so the script will continue to wait until both are up.
