Further attempting to localize the problem, I found a pickled form of
the metadata in /var/lib/cloud/instances/i-325d4c56/obj.pkl which
included the public ssh key, so it's definitely getting the data from
the metadata service.

Ok, I've been on the CC list for that bug for a long time, but I
missed that they actually made a decision. I'll just bite my tongue
on that one; at least it's not completely broken anymore.

Thanks for that link!

As it turns out, I just booted an Ubuntu Oneiric instance, and it does
not have a zeroconf route, but is still able to access the metadata
service, so it looks like this was a red herring. Back to the drawing
board.
