Comment 21 for bug 1671927

Jon,
That seems like a bug in your openstack. The point of 'latest' is that it is supposed to just be a copy of the "latest" (which would be 2015-10-15 for you). It should have the network-data.json file.

the code that generates that is in
https://github.com/openstack/nova/blob/master/nova/api/metadata/base.py

From the openstack that I can get at, I see network_data.json available in 2015-10-15 (liberty) and later which aligns with what the code says should be there.

$ mount /dev/sr0 /mnt
$ ( cd /mnt && find * -type f )
