Hi Benedikt,

Mi intend here was to have the debconf prompt happen only once when
installing the metadata server. So I was simply re-using the same
debconf variable. Obviously, this was a bad idea.

This last commit should be fixing your issue when using puppet:
http://anonscm.debian.org/cgit/openstack/neutron.git/commit/?id=5c17e246c7e1ed00a7f58ba1be98ab0185d25b81

Please give me your comments about it, then I'll upload it if you all
think it's ok.

Cheers,
