+# NixOS
+
+Ce repo contient la configuration NixOS des différentes machines présentes dans
+l'infrastructure de Aurore et ce décompose en plusieurs partie :
+
+- [hosts](./hosts) : contient la configuration spécifique à chaque machine,
+  typiquement la configuration réseau,
+- [profiles](./profiles) : contient la configuration des différents modules
+  utilisé,
+- [disks](./disks) : contient la configuration [disko](https://github.com/nix-community/disko)
+  des machines.
+
+## Installation d'une machine
+
+Si la configuration est déjà écrite, il faut alors suivre les étapes
+suivantes :
+
+1. S'assurer que la machine a accès à internet et possède un serveur DNS,
+1. Importer les fichiers de configurations,
+1. Si nécéssaire, il faut de générer le fichier `hardware-configuration.nix`
+   à l'aide de la commande `nixos-generate-config --no-filesystems --root .`
+   puis de l'ajouter dans la configuration,
+1. Vérifier que la configuration `disko` utilisée est compatible, la
+   commande `lsblk` devrait être suffisant pour cela,
+1. Partitionner les disques : l'usage de `disko` simplifie cette étape. En
+   effet, il suffit d'exécuter la commande :
+   `nix run github:nix-community/disko --extra-experimental-features "nix-command flakes" -- --mode disko --flake <path>#<nom>`
+   `disko` s'occupe automatiquement du montage des partitions créer,
+1. Créer le répertoire `/mnt/etc/nixos` et ajouter les fichiers de
+   configuration dans ce répertoire,
+1. Installer NixOS : `nixos-install --flake <path>#<nom>`,
+1. Si tout s'est bien passé, un mot de passe vous sera demandé pour le mot
+   de passe root. Entrer celui-ci puis `poweroff` ou `reboot`.
+1. Penser à push la configuration ainsi écrite.
+
+Remarque :
+
+> S'il n'y a pas suffisamment de place mémoire sur le disque d'installation
+> lors du partitionnement des disques avec disko, il est possible d'étendre le
+> nix-store en utilisant la RAM à l'aide de la commande :
+> `mount -o remount,size=3G,noatime /nix/.rw-store`
+> Cependant, cela peut être risquer s'il n'y a pas suffisamment de RAM.
