Thanks for your help

So I managed to install imagefactory using setup.py sdist and grepping
the rpm spec file for dependency but did not get very far.
It seems to use a daemon somewhere but without documentation it's very
much a time consuming trial and error.

I had a look at oz too, since it's packaged in Debian and was a bit
disappointed to see its 737 line long
/usr/lib/python2.7/dist-packages/oz/Debian.py unpacks a debian iso to
modify the boot parameter.
Also I could not get it to work to create a Debian 8 image, it fails
downloading the iso.

So it looks oz is not up to the task for the job it would need serious
work, so I am going to stick with packer ( or maybe virt-install ) for
the momment.

I also found out this week it's trivial to create a debian image using
virt-install from the libvirt folks with a preseed file. Works in text
mode, don't require an ISO, as non root.

virt-install \
--connect qemu:///session \
--name debian \
--ram 512 \
--vcpus 1 \
--file debuan.qcow2 \
--file-size=4 \
http://httpredir.debian.org/debian/dists/stable/main/installer-amd64/ \
--virt-type kvm \
--os-variant Debian8 \
--network=user \
--noreboot \
--graphics none \
--console pty,target_type=serial \
--extra-args "auto=true hostname=debian domain=
console=ttyS0,115200n8 DEBIAN_FRONTEND=text"
