I just returned from the MiniDebConf in Cambridge, where I gave two talks. One about building disk images (also for cross architecures) using fai-diskimage with FAI and the other about making d-i easier for beginners. The ideas for this talk were also the inspiration for creating the FAI.me web page. Making the usage of FAI easier, using it without installing it. Is this FAI as a service (FaaS)?
On the web page you can easily configure a customized installation image which will then be created for you. Booting this image, you will get a fully unattended installation, based on FAI technique and all software packages are already included on the installation image. The announcement has more details. I'm very excited to get your feedback for this project.
