====== Linux From Scratch ======


http://fr.linuxfromscratch.org/view/lfs-9.1-systemd-fr/index.html

Fonctionnement général: à partir d'un système existant, on construit LFS sur une partition à côté du système existant. On pourra ensuite booter sur LFS situé sur la nouvelle partition.

Dans une machine virtuelle avec 80 Go de stockage et 2 Go de RAM, installer une Debian Stable, en partitionnant comme suit:
  * 20 Go pour le système hôte, type ext4, monté sur / avec l'indicateur d'amorçage
  * 55 Go pour LFS, type ext4, non monté
  * le reste pour le swap


==== Prérequis du système hôte ====

Exécuter le script fournit [[http://fr.linuxfromscratch.org/view/lfs-systemd-stable/chapter02/hostreqs.html#__do_not_save__|ici]].

Correction à apporter:
  * faire pointer ''/bin/sh'' vers ''bash'' au lieu de ''dash'' ([[https://askubuntu.com/questions/328364/bin-sh-is-a-symbolic-link-that-doesnt-point-to-bin-bash#comment1744192_328368|Source]]): <code bash>
sudo dpkg-reconfigure dash
</code>
  * installer les paquets ''build-essential bison gawk m4 texinfo''



==== Définir la variable $LFS ====

<code bash>
export LFS=/mnt/lfs
</code>



==== Monter la nouvelle partition ====

<code bash>
sudo mkdir -pv $LFS
sudo mount -v -t ext4 /dev/<xxx> $LFS
</code>


==== Téléchargement des sources ====

<code bash>
sudo mkdir -v $LFS/sources
sudo chmod -v a+wt $LFS/sources
wget http://fr.linuxfromscratch.org/view/lfs-9.1-systemd-fr/wget-list
sudo wget --input-file=wget-list --continue --directory-prefix=$LFS/sources
</code>


==== Créer le répertoire $LFS/tools ====

Passer root, c'est bien plus simple (ne pas oublier de définir ''$LFS'' !).

<code bash>
mkdir -v $LFS/tools
ln -sv $LFS/tools / # '/tools' -> '/mnt/lfs/tools'
</code>



==== Ajouter l'utilisateur LFS ====

<code bash>
groupadd lfs
useradd -s /bin/bash -g lfs -m -k /dev/null lfs
passwd lfs
chown -v lfs $LFS/tools
chown -v lfs $LFS/sources
</code>

Se connecter avec l'utilisateur ''lfs''.


==== Configurer l'environnement ====

<file bash ~/.bash_profile>
exec env -i HOME=$HOME TERM=$TERM PS1='\u:\w\$ ' /bin/bash
</file>

<file bash ~/.bashrc>
set +h
umask 022
LFS=/mnt/lfs
LC_ALL=POSIX
LFS_TGT=$(uname -m)-lfs-linux-gnu
PATH=/tools/bin:/bin:/usr/bin
export LFS LC_ALL LFS_TGT PATH
</file>

<code bash>
source ~/.bash_profile
</code>

Si on redémarre la machine maintenant, il faut monter la partition dans ''$LFS'' et se connecter avec l'utilisateur ''lfs'', tout est déjà défini.
