Hi Anders,

the scenario you wrote above would also be interesting, but it is not what
I propose (and on the AWS, I am not able to use debian-installer to overwrite
itself on the same volume).

The idea is rather to have machine images of the stable debian-installer (which are
easy to maintain because it is rarely updated), use them to install Debian
on a volume attached at boot time, and register the volume as a new image.

It almost works.  My main problem is that on the AWS it is usual for the images
to be insalled on an unpartitionned volume, and debian-installer does not seem
to be able to do this.  But I think that it is not a fundamental limitation.

I blogged about my latest progresses here:


As you can see, creating images of the debian-installer is very straightforward,
and then creating Debian images using debian-installer is only a matter of
writing a preseed file.

Have a nice Sunday,
