bootstrap-vz
bootstrap-vz is a bootstrapping framework for Debian. It is is specifically targeted at bootstrapping systems for virtualized environments. bootstrap-vz runs without any user intervention and generates ready-to-boot images for a number of virtualization platforms. Its aim is to provide a reproducable bootstrapping process using manifests as well as supporting a high degree of customizability through plugins.
bootstrap-vz was coded from scratch in python once the bash script architecture that was used in the build-debian-cloud bootstrapper reached its limits.
