# Linux From Scratch pour Raspberry Pi

{{INLINETOC}} 

Cet article déroule les étapes nécessaires à la construction d'un système LFS spécifique à Pi.

Ce guide a été testé et vérifié sur une carte SD SanDisk de 32 Go avec Raspbian Buster (2020-05-27) comme système hôte, mais la plupart des distributions Linux devraient pouvoir fonctionner comme plate-forme hôte pour faire un build LFS si les outils requis peuvent être ajouté. La taille minimale de la carte SD est probablement de 4 Go. 

Le temps de construction total est compris entre 60 heures sur RPi 1 et 8 heures sur RPi 4.

## Image de base de la carte SD LFS

Le site https://intestinate.com/pilfs/ propose des images précompilées de la toolchain LFS, on peut utiliser une de ce images comme base pour un projet ou comme environnement de construction dans lequel construire une distribution en suivant le guide PiLFS.

Pour se connecter en tant que root utiliser le mot de passe **pilfs**

<WRAP tip>Pour se connecter à un point d'accès Wi-Fi renseigner le mot de passe dans le fichier `wpa_supplicant`:\\ \\ `wpa_passphrase your_SSID your_password > /etc/sysconfig/wpa_supplicant-wlan0.conf`\\ \\ DHCP est actif par défaut, pour utiliser une adresse statique, modifier `/etc/sysconfig/static.eth0`</WRAP>

Quelques packages supplémentaires ont été ajoutés pour plus de commodité, par ex. sshd, wget, tmux, git et la mise à jour rpi de Hexxeh

Il y en a une liste dans `/usr/src/installed_tarballs.txt`


## Construction de la Toolchain avec les sources

Le site https://intestinate.com/pilfs/ propose un ensemble de scriptes permettant de construire un toolchain LFS

### Préparation de la distribution [2.2. Configuration système hôte requise]

Il est préférable d'avoir la quantité maximale de RAM disponible pour la construction. Utiliser soit raspi-config pour réduire la quantité de mémoire allouée au GPU (graphique) à 16, ou ajouter `gpu_mem=16` à /boot/config.txt et redémarrer.

Si on utilise un Pi avec 256 Mo de RAM, on aura besoin d'un espace de swap.

Sur Raspbian, définir un mot de passe root avec `sudo passwd root` et se connecter en tant que root.

Ajouter les paquets prérequis :

```
apt update
apt install bison gawk m4 texinfo
```


### Ajouter une partition LFS [2.4. Création d'une nouvelle partition]


Utiliser **fdisk** ou **cfdisk** pour travailler sur la table de partition de la carte SD :

```
cfdisk /dev/mmcblk0
```

  * **mmcblk0p1** est la partition FAT32 qui est montée sous /boot et contient le chargeur de démarrage et le noyau Linux.
  * **mmcblk0p2** contient le système hôte.

Sélectionner l'espace libre et créer une nouvelle partition principale avec l'espace restant. Il faut ensuite écrire les modifications sur le disque avant de quitter. Il faudra peut-être redémarrer à ce stade pour que Linux puisse voir la nouvelle partition.

<WRAP info>Il n'est pas nécessaire de créer une partition de swap dédiée ! Un fichier d'échange peut être ajouté à tout moment ultérieurement et est plus flexible tout en offrant les mêmes performances.</WRAP>

### Création d'un système de fichiers ext4 [2.5. Création d'un système de fichiers sur la partition]

Utiliser la commande suivante pour créer un système de fichiers ext4 sur la nouvelle partition :

```
mkfs.ext4 -m 1 -L MyLFS /dev/mmcblk0p3
```

### Paramétrage de la variable $LFS [2.7. Montage de la nouvelle partition]

Pour construire sur une nouvelle partition, procéder comme suit :

```
export LFS=/mnt/lfs
mkdir -pv $LFS
mount -v -t ext4 /dev/mmcblk0p3 $LFS
```

Pour construire dans un répertoire faire simplement ceci :

```
export LFS=/lfs
mkdir -pv $LFS
```

### Récupérer tous les paquets [3.1. Introduction]

Étant donné que le Pi a besoin d'un ensemble de packages et de correctifs légèrement différent, utiliser  la wget-list suivante pour tout récupérer (y compris les scripts de construction, etc.) :

```
mkdir -v $LFS/sources
chmod -v a+wt $LFS/sources
cd $LFS/sources
wget https://intestinate.com/pilfs/scripts/wget-list
wget --input-file=wget-list --continue --directory-prefix=$LFS/sources
```

### Réglage de l'environnement utilisateur lfs [4.4. Configuration de l'environnement]

<WRAP important>Remplacer `LFS=/mnt/lfs` par `LFS=/lfs` si on ne construit pas sur une nouvelle partition.\\ \\ La variable **LFS\_TGT** doit être changée en **LFS\_TGT=$(uname -m)-lfs-linux-gnueabihf**</WRAP>

### Build Chapitre 5 & 6 [5.2. Binutils - Passe 1]

<WRAP tip>Comme la construction est relativement longue il est recommandé de démarrer une session **tmux**((**tmux** est un multiplexeur de terminal. Il permet de basculer facilement entre plusieurs programmes dans un terminal, de les détacher pour continuer de fonctionner en arrière-plan et de les rattacher à un autre terminal.)) ou **screen**((**screen** est un gestionnaire de fenêtres plein écran qui multiplexe un terminal physique entre plusieurs processus, généralement des shells interactifs. Lorsque **screen** est appelé, il crée une fenêtre unique, ensuite, à tout moment, on peut créer de nouvelles fenêtres avec d'autres programmes, tuer la fenêtre actuelle, afficher une liste des fenêtres actives, activer et désactiver la connexion de sortie, copier du texte entre fenêtres, afficher l'historique de défilement, basculer entre les fenêtres, etc. Toutes les fenêtres exécutent leurs programmes de manière totalement indépendante les unes des autres. Les programmes continuent de s'exécuter lorsque leur fenêtre n'est actuellement pas visible et même lorsque toute la session d'écran est détachée du terminal de l'utilisateur..)), parce que si on interromp la connexion ssh ou si le routeur a un problème, la construction s'arrêtera tout simplement.</WRAP>

Il faut d'abord éditer le script **ch5-build.sh** pour placer le modèle Pi en haut. Ensuite, commencer la construction comme ceci:

```
cd $LFS/sources
chmod +x ch5-build.sh
./ch5-build.sh
```

Le script affichera le temps SBU après la fin de la première construction de binutils.

### Build Chapitre 7 [7.7. Libstdc++ de GCC - Passe 2]

Avant d'entrer dans le chroot et de commencer la construction, éditer le script **ch7-build.sh** pour définir quelques paramètres facultatifs en haut. Entrer ensuite le chroot et exécuter le script :

```
cd/sources
chmod +x ch7-build.sh
./ch7-build.sh
```
### Présentation des scripts d'amorçage PiLFS [9.6. Utilisation et configuration du script de démarrage System V]

Le Pi n'a pas de moyen de garder le temps entre les redémarrages. Lorsqu'il démarre, il n'a aucune idée de l'heure qu'il est jusqu'à ce qu'il puisse récupérer l'heure correcte à partir d'un serveur NTP.

Pour résoudre ce problème et quelques autres éléments spécifiques à Pi, quelques scripts de démarrage provenant de différentes sources ont été regroupés dans une archive tar pour une installation facile, ajouter ces quatre scripts :

```
make install-networkfix install-swapfix install-fake-hwclock install-switch-cpu-governor
```

### Création du fstab [10.2. Création du fichier /etc/fstab]

Tout d'abord, un fstab adapté à la nouvelle méthode de partition. Ici, on prend la partition de l'ancienne distribution et on la transforme en un espace dédié aux répertoires personnels de l'utilisateur (il faudra évidemment effacer l'ancien contenu après le premier démarrage).

```
/dev/mmcblk0p1 /boot        vfat     defaults            0     0
/dev/mmcblk0p2 /home        ext4     defaults,noatime    0     1
/dev/mmcblk0p3 /            ext4     defaults,noatime    0     2
#/swapfile     swap         swap     pri=1               0     0
proc           /proc        proc     nosuid,noexec,nodev 0     0
sysfs          /sys         sysfs    nosuid,noexec,nodev 0     0
devpts         /dev/pts     devpts   gid=5,mode=620      0     0
tmpfs          /run         tmpfs    defaults            0     0
devtmpfs       /dev         devtmpfs mode=0755,nosuid    0     0
```

Si on opte pour la méthode de remaniement PC, fstab ressemblera plutôt à ceci :

```
/dev/mmcblk0p1 /boot        vfat     defaults            0     0
/dev/mmcblk0p2 /            ext4     defaults,noatime    0     1
#/swapfile     swap         swap     pri=1               0     0
proc           /proc        proc     nosuid,noexec,nodev 0     0
sysfs          /sys         sysfs    nosuid,noexec,nodev 0     0
devpts         /dev/pts     devpts   gid=5,mode=620      0     0
tmpfs          /run         tmpfs    defaults            0     0
devtmpfs       /dev         devtmpfs mode=0755,nosuid    0     0
```

### Noyau, chargeur de démarrage et micrologiciel [10.3. Linux]

Bien qu'on puisse potentiellement créer un noyau Linux, il est préférable de s'assurer d'abord que le système démarre correctement avec le noyau de la Fondation Raspberry Pi.

Il n'y a pas de GRUB sur le Pi, et on compte plutôt sur le chargeur de démarrage de la Fondation Raspberry Pi pour nous démarrer.

Si on a ajouté une nouvelle partition LFS, quitter le chroot à ce stade et éditer `/boot/cmdline.txt`. Il faut remplacer `root=/dev/mmcblk0p2` par `root=/dev/mmcblk0p3` afin que le chargeur de démarrage utilise la nouvelle partition LFS comme système de fichiers racine.

Certains composants de la carte Raspberry Pi, comme les contrôleurs Wi-Fi et Bluetooth, nécessitent le chargement des blobs binaires du micrologiciel au démarrage. Ce sont des fichiers stockés dans `/lib/firmware` et le moyen le plus simple de les obtenir est simplement de les copier à partir de Raspbian ou de l'image de base PiLFS.

### Fin [11.3. Redémarrage du système]

Alors voilà. le système est maintenant amorçable et on peut ajouter quelques éléments avant de l'utiliser (dhcpcd, wget, OpenSSH et ntp).

## Dépannage

### Réparation de la carte SD

Maintenant, on va voir le processus de réparation de le carte SD sur un PC Linux.

Monter la partition de données endommagée:

```
mount /dev/sdb2 /mnt
```

Ensuite, effacer tout sauf le répertoire /lfs, comme ceci :

```
cd /mnt
shopt -s extglob
rm -rf !(lfs)
```

Et maintenant on recopie l'ancien root :

```
mv /mnt/lfs/* /mnt
```

La commande mv conservera toutes les autorisations de fichier par défaut, mais si on souhaite plutôt copier lre système LFS, il faut ajouter l'indicateur de conservation des autorisations à cp, c'est-à-dire `cp -rp`

### Créer une image de carte SD adaptée à la distribution

La partie délicate de la préparation d'une image de carte SD est qu'une copie d'image directe à l'aide de dd prend la même taille que l'ensemble de la carte SD. Voici comment préparer une image de carte SD à partir de zéro :

Tout d'abord, il faut s'assurer d'avoir une copie complète de tous les fichiers qui vont aller sur la carte, y compris les éléments qui vont sur la partition FAT32 comme le chargeur de démarrage et le noyau.

Ensuite, on doit recréer la table de partition à partir de zéro. Par exemple avec **Parted** pour l'édition de partition en raison de sa fonction d'alignement automatique. Effacer tout ce qui se trouve sur votre carte, puis créer une nouvelle table:

N'éditez pas le mauvais disque... triple-vérifiez ! :)

```
parted /dev/sdb
mkpart primary fat32 4 273
```

Cela crée la partition de démarrage FAT32, selon la disposition de Raspbian, d'une taille de 268 Mo.

Ensuite, nous créer la partition de données :

```
mkpart primary ext4 277 2000
```

Ici, on définit une image qui pourrait s'adapter parfaitement sur une carte SD de 2 Go.

Maintenant, si on affiche la table, on doit avoir quelque chose comme ceci :

```
Number  Start   End     Size    Type     File system  Flags
 1      4194kB  273MB   268MB   primary  fat32        lba
 2      277MB   2000MB  1723MB  primary  ext4
```

Maintenant qu'on a une nouvelle disposition de partition, formater les partitions, comme ceci :

```
mkdosfs -F 32 -n Pi-Boot -v /dev/sdb1
mkfs.ext4 -m 1 -L MyLFS /dev/sdb2
```

Copier ensuite toutes les binaires en place :

```
mount /dev/sdb1 /mnt
cp -rvp bootfiles/* /mnt
umount /mnt
mount /dev/sdb2 /mnt
cp -rvp lfsfiles/* /mnt
umount /mnt
```

Utiliser dd pour faire une image de la carte mais en inclueant toute la partition ext4 :

```
dd if=/dev/sdb of=mylfs.img bs=1M count=2000
```
