Which is expected: either you decide to use dbconfig-common and you have
the benefits of having the database syncs automated, either you do all
by hand. I have uploaded such change on all OpenStack packages and it
has been accepted by the release team this way, I do believe this will
increase reliability to do that.

Also, as I wrote previously, it is a way too late in the Jessie cycle to
add new debconf screens. If I do:
1/ The release team will refuse it
2/ The translators will scream (rightly)

I don't think this is a good idea. To me, either you use the full
automation, either you don't. I don't see the point in doing only half
of the things, and this may lead to errors. For example, a package would
try to do a dbsync but no database was created.

This assumption is simply wrong. By default, all packages have a DNS
connection= directive.

Have you seen the number of SQLite fixes that the Neutron package
carries? I really don't want to have to do that work again.

Please don't. If you decide to not use dbconfig-common, just do the db
sync by hand. I believe the puppet openstack scripts (which you are
using, right?) do it anyway.
