This is more or less what my openstack-cluster-installer is doing:
booting a live image over PXE+HTTP, and install Debian from there. See:
https://salsa.debian.org/openstack-team/debian/openstack-cluster-installer
which I'm going to present in Curitiba at Debconf 19.
The only bit which I don't have is the use of pre-built images to
install on a system. But that could be done. That's what fuel was doing:
prepare image on the PXE server, copy them over the network.
If we are to build such a new installer, then *please*, let's think
about building clusters as well, not just individual desktops.
Cheers,
