Only template is Debian 'Jessie' 8.0, which uses the beta 2 release of the i386 netinst cd. It is based on veewee's original Debian-7.6.0-i386-netboot template.
The original template doesn't preseed correctly, so some modifications to boot line and preseed.cfg were required.
- Some postinstall files like chef, puppet and ruby are disabled. Enable them if required.
- GRUB still may ask questions.
- The guest's apt uses host's apt-cacher-ng by default. Disable
apt-proxy.shpostinstall entry if you don't want this behaviour.
