Setup of grml-live build system
-------------------------------

The build system is a Debian/etch system (inside VMware) installed via grml-debootstrap.

Installation of software
~~~~~~~~~~~~~~~~~~~~~~~~

Add grml and FAI repository to Debian package list:

  cat >> /etc/apt/sources.list << EOF
  deb http://deb.grml.org/ grml-stable  main
  deb http://deb.grml.org/ grml-testing main

  deb http://fai-project.org/download etch koeln
  EOF

Pin down grml repository so only the packages manually chosen for installation
are taken from it:

  cat >> /etc/apt/preferences << EOF
  Package: *
  Pin: origin deb.grml.org
  Pin-Priority: 100
  EOF

Install working squashfs-tools:

  apt-get update
  apt-get install squashfs-lzma-tools

[NOTE]
Depending on which grml version your are remastering make sure to use the right
squashfs tools, please make sure to check out
link:http://grml.org/grml-live/#current_state[http://grml.org/grml-live/#current_state]!

Install grml-live and additional software for comfortable console work:

  apt-get install zsh grml-live mercurial gpm asciidoc

  mkdir ~/bin && cd ~/bin
  wget http://grml.org/scripts/grml-config.sh
  chmod 775 grml-config.sh
  cd && ~/bin/grml-config.sh

Configuration of custom ISO
~~~~~~~~~~~~~~~~~~~~~~~~~~~

Copy grml-live templates:

  cp -a /usr/share/grml-live/templates ~/

Now we can adjust configuration
link:isolinux.cfg[templates/boot/isolinux/isolinux.cfg] according to our needs
(like get "forensic" and "lang=de" bootoptions by default).

Prepare local configuration (adjust it according to your personal needs):

  cat > /etc/grml/grml-live.local << EOF
  # Main output directory
  OUTPUT="/grml/grml-live"
  #ZERO_LOGFILE='1'
  #ZERO_FAI_LOGFILE='1'

  #GRML_LIVE_SOURCES="
  #deb http://192.168.1.112/debian     lenny         main contrib non-free
  #deb http://deb.grml.org/            grml-stable  main
  #deb http://deb.grml.org/            grml-testing main
  #deb http://ftp.de.debian.org/debian lenny         main contrib non-free
  #"

  # FAI_DEBOOTSTRAP="lenny http://ftp.de.debian.org/debian"
  EOF

Create FORENSIC grml-live/FAI class with package list:

  cat >> /etc/grml/fai/config/package_config/FORENSIC << EOF
  PACKAGES aptitude

  afflib
  autopsy
  foremost
  libewf
  scalpel
  sleuthkit
  EOF

Create FORENSIC script for grml-live/FAI:

  mkdir /etc/grml/fai/config/scripts/FORENSIC

  cat > /etc/grml/fai/config/scripts/FORENSIC/01-create-forensic-dir << EOF
  #!/bin/sh
  # Filename:      /etc/grml/fai/config/scripts/FORENSIC/01-create-forensic-dir
  # Purpose:       create directory "/forensic" in chroot

  set -e

  [ -d "$target"/forensic ] || mkdir "$target"/forensic

  EOF

  chmod 775 /etc/grml/fai/config/scripts/FORENSIC/01-create-forensic-dir

Build ISO
~~~~~~~~~

Execute grml-live as root to build ISO in /grml/grml-live/grml_isos:

  grml-live -s lenny -a i386 -c GRMLBASE,GRML_MEDIUM,FORENSIC,I386 -t ~/templates -V
