It is a bad idea to recommends/depends on an SQL server, as typically,
you would install a MySQL-Galera / Mariadb-Galera cluster, and you'd be
using networking. So I don't think that's something we should do.

The one you will want to run... ;) You need to understand how Neutron
works, and select the type of networking you'll use: VXLan, Linux
bridge, GRE tunneling, SR-IOV are things you need to decide on.

Ironic works together with a nova-compute, it can't be used alone.

I mean that you must choose to *either* use Jessie + Jessie-backports,
*OR* testing (in which case you'll need to upgrade to it).

Well, since you didn't understand that nova-compute needs to be setup to
run Ironic, your installation must be quite wrong. I'd suggest reading
more docs.

Feel free to file bugs for it, and we'll fix. There's also this one:
http://docs.openstack.org/draft/install-guide-debconf/

which will be the place where all things debconf (ie: without disabling
prompts) will be documented from now on.

The one which will have all the API running.

It preseeds all answers and provides a hands-off installation. Then
you'll have all passwords written in osinstallrc.

As I wrote, to get Ironic working, you need nova-compute working.

I don't know.
