● Introduction● bsdinstall script extention● FAI - Fully Automatic Installer
as a distro● Netbooting FAI● Universal FAI● DEMO

INTRO
● Google Summer of Code 2014 project● provide a non interactive, unattended
FreeBSD installation process from the network
● without NFS server● extension for scripted bsdinstall● booting the FAI (Fully AutomaticInstaller) from the network by PXE
● based on mfsBSD● simple usage, without high barrier to
entry

bsdinstall script extention
● more parameters
● division installation into 3 parts:DEVICE PREPARATIONINSTALLATIONCONFIGURATION

● one image for different configurations
● how to tell FAI where the configuration file is?
● add option bootfile-name"http://example.com/mfsbsdfai/";
● FAI tries to download file called the same as the MAC address, or default
