GRML

GRML ist mein bevorzugtes ISO-Linux. Leider keine recht neuen Releases mehr (Stand 10/2018: Release 2017.05). Aber das muss nicht sein.

Alles was man braucht gibts unter https://github.com/grml/grml-live.

Vorraussetzungen

apt-get install git build-essential fai-quickstart isolinux mtools mmd dosfstools memtest86+ 

Bauen

#!/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/

Am besten das ganze gleich in eine build.sh verpacken.

Anpassen

Die Konfig fuer Anpassungen befindet sich unter etc/grml/grml-live.conf.

Die beiden oben stehenden Aenderungen fuehren dazu, dass

  1. ISOLINUX von der seriellen Konsole zu errechen ist („die erste“ und 115200 Baud)
  2. Linux auch von dieser zu errechen ist.
