Hello, I think that this question was resolved a long time ago, but I did not
found an answer from the cloud team.
I need to create a bunch of vm image for an openstack instance. In this images,
we need to install a bunch of software, Debian packages, pure binary packages,
and does some customisation of the configuration for these packages.
So I would like to know which tool should be use for this purpose.
thanks for your consideration and I am sorry if this question has already a
definitive answer :)

Hi Frederic,
There's absolutely no definitive answer, building an image is quite an
easy thing to do if you understand the topic well enough, and there are
myriads of tools for it. So let me just point you to what I did myself
and extensively used (which is obviously biased).
You may want to give a try to:
https://packages.debian.org/openstack-debian-images
That's not the tool used by the debian-cloud team anymore, but it was
used for at least 3 releases of Debian in the past. It's controlled
fully on the command line, it's just a simple (not-so-long) script
shell, so it's easy to customize. There's also a hook for it (see the
end of the man page for that).
These days, I use it mostly for setting-up bare-metal servers, but it's
perfectly valid for building images. I use it also for automating the
process of building images for Octavia and Manila.
I hope this helps,
Cheers,

P.S: I wouldn't recommend at all using d-i in this process, neither
re-using a customized OpenStack VM snapshot which will be tainted.
