+====== FAI @ grml ======
+===== Install packages =====
+<code>
+aptitude install fai-server fai-doc
+</code>
+===== Adjust FAI server =====
+Adjust configuration:
+<code>
+/etc/fai/fai.conf              -> adjust FAI_CONFIGDIR
+/etc/fai/make-fai-nfsroot.conf -> adjust NFSROOT and FAI_DEBOOTSTRAP
+/etc/fai/apt/sources.list      -> adjust mirrors
+mkdir -p /grml/fai/config
+cp -a /usr/share/doc/fai-doc/examples/simple/* /grml/fai/config/
+</code>
+Invoke fai dirinstall:
+<code>
+mount -o remount,suid,dev,rw /dev/shm
+fai -v -cFAIBASE -u grml dirinstall /dev/shm/fai
+chroot /dev/shm/fai bash
+</code>
+===== Adjust for GRML =====
+Package selection example:
+<code>
+cd /grml/fai/config/package_config
+cat > GRML << EOF
+PACKAGES aptitude
+vim-full
+EOF
+</code>
+Adjust stuff like TIMEZONE=Europe/Vienna, ROOTPW='x',... for GRML-class:
+<code>
+cd /grml/fai/config/class
+cp FAIBASE.var GRML.var
+vim GRML.var
+</code>
+Execute scripts during fai dir-install:
+<code>
+cd /grml/fai/config/scripts/
+mkdir GRML
+cat > 10-helloworld << EOF
+#!/bin/sh
+echo Hello World
+EOF
+chmod 755 10-helloworld
+</code>
+Don't forget to invoke fai with GRML class:
+<code>
+fai -v -cFAIBASE,GRML -u grml dirinstall /dev/shm/fai
+</code>
+Check log files of GRML:
+<code>
+root@grml ~log/fai/dirinstall/grml # l
+total 204
+-rw-r--r-- 1 root root   235 2007-08-26 11:20 cfagent.log

+===== Tips =====
+[[http://fai-project.org/download/mkdebmirror|mkdebmirror]]: create local Debian mirror
+Important variables for scripts:
+<code>
+$ROOTCMD => execute command inside target chroot
+$target  => points to target chroot
+</code>
+Important commands for scripts:
+<code>
+fcopy    => copy files to target chroot
+ainsl    => append if no such line (in file)
+</code>
+Adjust 'PACKAGES $COMMAND', check possible values via:
+<code>
+install_packages -H
+</code>
+Create tarball for basic chroot:
+<code>
+mkdir /dev/shm/deboot
+debootstrap etch /dev/shm/deboot http://ftp.de.debian.org/debian
+cd /dev/shm/deboot && tar zcf base.tgz ./
+grep NFS /etc/fai/make-fai-nfsroot.conf
+NFSROOT=/grml/fai/nfsroot
+mkdir -p /grml/fai/nfsroot/live/filesystem.dir/var/tmp
+mv /dev/shm/deboot/base.tgz /grml/fai/nfsroot/live/filesystem.dir/var/tmp/
+Now you should see
+Extracting /grml/fai/nfsroot/live/filesystem.dir/var/tmp/base.tgz
+when invoking:
+fai -v -cFAIBASE,GRML -u grml dirinstall /dev/shm/fai
+</code>
+Build NFS-root (uses NFSROOT from /etc/fai/make-fai-nfsroot.conf) and bootable CD-ISO:
+<code>
+make-fai-nfsroot -v
+mkdir /grml/tmp_mirror
+fai-mirror -c DEFAULT,I386,FAIBASE,GRML -v /grml/tmp_mirror
+fai-cd -m /grml/tmp_mirror /grml/fai.iso
+</code>
