FAI stands for Fully Automatic Installation and is software that enables the automatic installation and configuration of GNU/Linux. The unattended installation of entire computer clusters is made easy with FAI. FAI was originally developed to install Debian, but can also install other distributions. Perl, Shell, or Cfengine scripts can be used to modify the systems’ configuration files. FAI is utilized by the web-based management interface GOsa, which is used by the City of Munich for Linux migration.
FAI is free software and can be downloaded from the project page.
