Before starting your installation, you should spend much time in planning your installation. When you're happy with your installation concept, FAI can do all the boring, repetitive tasks to turn your plans into practice. FAI can't do good installations if your concept is imperfect or lacks some important details. Start planning the installation by answering the following questions:
You also have to think about user accounts, printers, a mail system, cron jobs, graphic cards, dual boot, NIS, NTP, timezone, keyboard layout, exporting and mounting directories via NFS and many other things. So, there's a lot to do before starting an installation. And remember that knowledge is power, and it's up to you to use it. Installation and administration is a process, not a product. FAI can't do things you don't tell it to do.
But you need not to start from scratch. Look at all files and scripts in the
configuration space. There are a lot of things you can use for your own
installation. A good paper with more aspects of building an infrastructure is
