====== GRML ======
GRML ist mein bevorzugtes ISO-Linux. Leider keine recht neuen Releases mehr (Stand 10/2018: Release 2017.05). Aber das muss nicht sein.
===== Selber bauen =====
Alles was man braucht gibts unter [[https://github.com/grml/grml-live]].
==== Vorraussetzungen ====
<code bash>
apt-get install git build-essential fai-quickstart isolinux mtools mmd dosfstools memtest86+ 
</code>

==== Bauen ==== 
<code bash>#!/bin/bash

export GRML_FAI_CONFIG=$(pwd)/etc/grml/fai
export SCRIPTS_DIRECTORY=$(pwd)/scripts
export LIVE_CONF=$(pwd)/etc/grml/grml-live.conf
./grml-live -s sid -a amd64 -c GRMLBASE,GRML_FULL,AMD64 -t $(pwd)/templates/</code>
Am besten das ganze gleich in eine build.sh verpacken.
==== Anpassen ====
Die Konfig fuer Anpassungen befindet sich unter etc/grml/grml-live.conf.

Ausgehend von GIT hash dadd8e03c24baeadd3716d0826626aa78bfa1226

Die beiden oben stehenden Aenderungen fuehren dazu, dass
  - ISOLINUX von der seriellen Konsole zu errechen ist ("die erste" und 115200 Baud)
  - Linux auch von dieser zu errechen ist.
