<p><a href="https://wiki.archlinux.fr/Chroot">Adaptation de larticle chroot du wiki archlinux (fr)</a></p>
<p>Le <code class="language-plaintext highlighter-rouge">chroot</code> (abréviation de <strong>CH</strong>anging <strong>ROOT</strong>) est un processus qui permet de changer la racine en entrant dans un environnement isolé. Un programme lancé dans cet environnement ne peut pas accéder aux fichiers et aux commandes du système hôte. Cet environnement modifié est appelé <em>chroot jail</em> (une prison).</p>
<h3 id="quand-chrooter">Quand chrooter</h3>
<p>Le chroot est généralement utilisé pour dépanner des systèmes qui ne démarrent pas ou bien où le logging est impossible. Quelques exemples courants :</p>
<ul>
<li>Réinstaller le <a href="https://wiki.archlinux.fr/Cat%C3%A9gorie:Bootloader">chargeur de démarrage (bootloader)</a>.</li>
<li>Reconstruire les <a href="https://wiki.archlinux.fr/Mkinitcpio#G.C3.A9n.C3.A9rer_l.27image">initramfs</a>.</li>
<li>Mettre à jour ou bien <a href="https://wiki.archlinux.fr/Downgrade">rétrograder des paquets</a>.</li>
<li>Réinitialiser un <a href="https://wiki.archlinux.org/index.php/Reset_root_password">mot de passe oublié</a>.</li>
</ul>
<p>Cette méthode présente toutefois des limitations (voir <a href="http://en.wikipedia.org/wiki/Chroot#Limitations">Wikipedia (en)</a>).</p>
<h3 id="exigences">Exigences</h3>
<p>Avant de chrooter, assurez-vous de :</p>
<ul>
<li>Avoir le privilège root.</li>
<li>Avoir un autre environnement GNU/Linux, tel un LiveCD/USB, ou bien depuis une autre installation existante.</li>
<li>Avoir la même architecture entre les deux environnements (cest-à-dire être depuis une distribution x86_64 pour chrooter une Arch x86_64). On peut trouver larchitecture de lenvironnement courant avec la commande uname -m (le résultat étant i686 ou bien x86_64).</li>
<li>Avoir les modules noyaux nécessaires chargés qui serviront dans lenvironnement chrooté.</li>
<li>Avoir son swap activé si nécessaire (swapon /dev/sdXY.</li>
<li>Avoir une connexion Internet fonctionnelle si nécessaire.</li>
</ul>
<h3 id="montage-des-partitions">Montage des partitions</h3>
<p>Pour chrooter dans un système sur lequel vous navez pas démarré, il faut préparer un minimum lenvironnement. Prenons le cas où vous devez utiliser votre système Arch depuis un autre système GNU/Linux (LiveCD, autre installation, …); en supposant que vous utilisez le dossier /mnt, vous devez monter au minimum les dossiers suivants:</p>
<p><strong>Astuce:</strong> Vous venez de charger un LiveCD, et vous auriez plus de facilités en utilisant votre clavier français ; faites :<br />
<code class="language-plaintext highlighter-rouge">loadkeys fr</code></p>
<p><strong>Note:</strong> Si vous utilisez <a href="https://wiki.archlinux.fr/LVM">LVM</a>, munissez-vous dun LiveCD le supportant (celui dArch par exemple) et avant les opérations de montage, activez-le en lançant :<br />
<code class="language-plaintext highlighter-rouge">vgchange -a y</code></p>
<p>Vous pouvez utiliser les commandes <strong>lsblk</strong>, <strong>fdisk -l</strong> ou <strong>blkid</strong> pour trouver les partitions de votre système.</p>
<p>Une fois les partitions repérées, procédez au montage :<br />
<code class="language-plaintext highlighter-rouge">mount /dev/sdXY /mnt</code></p>
<p><strong>Note:</strong> <strong>/dev/sdXY</strong> étant la partition de votre <strong>racine (/)</strong>.</p>
<p>Noubliez pas de monter les partitions séparées si besoin (/boot, /boot/efi (la partition d<a href="https://wiki.archlinux.fr/ESP">ESP</a>, /home, /usr, /var, …) dans le sous-répertoire approprié de /mnt.</p>
<h3 id="changement-de-racine-passage-en-chroot">Changement de racine, passage en “chroot”</h3>
<p>Il existe plusieurs méthodes pour procéder au chroot:</p>
<ul>
<li>La première méthode étant propre à Arch</li>
<li>La deuxième méthode plus générique dans le monde UNIX</li>
<li>La troisième méthode étant propre à Systemd.</li>
</ul>
<h4 id="méthode-1--en-utilisant-arch-chroot">Méthode 1 : en utilisant arch-chroot</h4>
<p>Si vous êtes depuis le LiveCD dArch ou bien depuis une autre Arch où le paquet <a href="http://www.archlinux.org/packages/?arch=any&amp;arch=i686&amp;arch=x86_64&amp;q=arch-install-scripts">arch-install-scripts</a> est installé, vous navez quune seule commande à faire (le script soccupant de préparer au mieux lenvironnement à chrooter).<br />
Pour un chroot habituel :</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>arch-chroot /mnt
</code></pre></div></div>
<p>Pour exécuter un autre shell dans lenvironnement chrooté (ici on veut utiliser Bash) :</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>arch-chroot /mnt /bin/bash
</code></pre></div></div>
<p>Pour exécuter une seule commande dans lenvironnement chrooté (par exemple mkinitcpio -p linux) :</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>arch-chroot /mnt /usr/bin/mkinitcpio -p linux
</code></pre></div></div>
<h4 id="méthode-2--en-utilisant-chroot">Méthode 2 : en utilisant chroot</h4>
<p>Il faut monter soi-même les systèmes de fichiers nécessaires au bon fonctionnement de lenvironnement chrooté (pour éviter les commandes à rallonge, on utilise volontairement à la fois des chemins absolus et relatifs, soyez prudent) :</p>
<div class="language-bash highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nb">cd</span> /mnt
mount <span class="nt">-t</span> proc proc proc/
mount <span class="nt">--rbind</span> /sys sys/
mount <span class="nt">--rbind</span> /dev dev/
</code></pre></div></div>
<p>Et optionnellement :</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>mount --rbind /run run/
</code></pre></div></div>
<p>Pour utiliser une connexion Internet dans lenvironnement chrooté, il faut copier les informations du DNS :</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>cp /etc/resolv.conf etc/
</code></pre></div></div>
<p>Astuce: Si vous souhaitez lancer des applications graphiques, vous serez peut-être amené à utiliser <code class="language-plaintext highlighter-rouge">xhost +</code> pour permettre au chroot daccéder à X, une fois fini noubliez pas denlever cette autorisation avec <code class="language-plaintext highlighter-rouge">xhost -</code>.</p>
<p>Enfin le chroot :</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>chroot /mnt /bin/bash
</code></pre></div></div>
<blockquote>
<p><strong>Note:</strong>Si vous voyez une erreur <br />
<code class="language-plaintext highlighter-rouge">chroot: cannot run command '/usr/bin/bash': Exec format error</code>, cest que larchitecture du système hôte est différente du système à chrooter. <br />
<code class="language-plaintext highlighter-rouge">chroot: '/usr/bin/bash': permission denied</code>, remonter la partition avec loption exec : <code class="language-plaintext highlighter-rouge">mount -o remount,exec /mnt</code>.</p>
</blockquote>
<p>Une fois le chroot effectué, vous aurez peut-être besoin de charger la configuration de Bash :</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>source /etc/profile
source ~/.bashrc
</code></pre></div></div>
<blockquote>
<p><strong>Astuce:</strong> Pour différencier lenvironnement chrooté, vous pouvez utiliser un prompt différent :<br />
<code class="language-plaintext highlighter-rouge">export PS1="(chroot) $PS1".</code></p>
</blockquote>
<h4 id="méthode-3--en-utilisant-systemd-nspawn">Méthode 3 : en utilisant systemd-nspawn</h4>
<p>Bien que cette méthode soit similaire, ce nest pas à proprement parler du chroot. Cette commande est plus puissante, elle virtualise lensemble du système à chrooter, comme si ce dernier était en cours dexécution. Cest similaire à démarrer un deuxième système dexploitation, ce nest pas une machine virtuelle mais un conteneur.</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>cd /mnt
systemd-nspawn
</code></pre></div></div>
<p>La syntaxe complète serait :</p>
<p>systemd-nspawn -b -D ~/MyContainer -n`</p>
<ul>
<li>Loption <strong>-b</strong> démarre le système du conteneur (avec le PID=1), au lieu de simplement y ouvrir un shell.<br />
Pour quitter une machine virtuelle lancée avec cette option, il faut exécuter le commande <code class="language-plaintext highlighter-rouge">poweroff</code> (en root) dans ladite machine, ou bien utiliser la commande <code class="language-plaintext highlighter-rouge">machinectl</code> depuis lhôte.</li>
<li>Loption <strong>-D</strong> spécifie le dossier-racine du conteneur.</li>
<li>Loption <strong>-n</strong> établit un réseau privé entre hôte et conteneur.<br />
Elle nest pas nécessaire pour connecter la machine à Internet; au contraire, elle implique davoir créé un réseau privé.</li>
<li>Disponible aussi loption <strong>bind</strong> qui permet de monter un répertoire de lhôte dans le conteneur<br />
par exemple : <code class="language-plaintext highlighter-rouge">--bind /var/cache/pacman/pkg:/var/cache/pacman/pkg-host</code></li>
</ul>
<p>Voir le <a href="https://wiki.archlinux.org/index.php/Systemd-nspawn">wiki (en)</a> pour plus de détails.<br />
<strong>Astuce:</strong> Depuis une machine Debian tournant avec systemd un paquet spécifique doit avoir été installé : <code class="language-plaintext highlighter-rouge">systemd-container</code>.</p>
<h3 id="quitter-le-chroot">Quitter le chroot</h3>
<p>Une fois les modifications terminées, utilisez exit pour sortir du chroot (ou encore Ctrl+D).<br />
<code class="language-plaintext highlighter-rouge">exit</code></p>
<p>Il faut enfin démonter ce que vous avez monté, en utilisant la commande umount:<br />
<code class="language-plaintext highlighter-rouge">cd /</code><br />
<code class="language-plaintext highlighter-rouge">umount --recursive /mnt/</code></p>
<p><strong>Note:</strong> Si un message tel <code class="language-plaintext highlighter-rouge">umount: /chemin: device is busy</code> apparaît, cest quun programme sexécute toujours dans le chroot. Le moyen le plus propre consiste à terminer ce programme, puis à utiliser la commande <code class="language-plaintext highlighter-rouge">mount</code> pour localiser la ou les partitions qui nont pas été démontées, puis dutiliser à nouveau <code class="language-plaintext highlighter-rouge">umount</code>. Si cela ne fonctionne toujours pas, utilisez <code class="language-plaintext highlighter-rouge">umount --force</code>, ou <code class="language-plaintext highlighter-rouge">umount --lazy</code> en dernier recours. Si le problème nest toujours pas résolu, préférez un redémarrage pour éviter de futur conflits.</p>
<p>Et éventuellement redémarrer:<br />
<code class="language-plaintext highlighter-rouge">reboot</code></p>
