Je vais parler ici de l'installation de ArchLinux sur mon ordinateur. Avec un peu de chance cela pourra être utile à d'autres et peut être même à toi!
Par contre je ne l'installerai jamais sur un serveur pour lequel je préfère debian. Mais c'est un autre sujet.
Note : Ce guide s'inspire largement de l'article d'installation officiel.

std.rocks has address 46.105.57.169
std.rocks has IPv6 address 2001:41d0:301::20
std.rocks mail is handled by 1 mx4.mail.ovh.net.
std.rocks mail is handled by 10 mx3.mail.ovh.net.
Note : à partir de cette étape, si besoin, il est possible de se connecter depuis une autre machine à l'installeur avec ssh. Il faudra juste utiliser la commande passwd avant pour paramétrer un mot de passe.

Je vais partitionner mon disque de 40G de la façon suivante.
| Partition | Note | Système de fichier | Taille |
|---|---|---|---|
| EFI | partition efi | FAT32 | 512M |

| swap | partition fichiers d'échange | swap sur LUKS | 2G |
| / | partition racine | btrfs sur LUKS | 37G |
⚠️ A noter que le disque sera complètement supprimé et par conséquent les données présentes seront effacées.⚠️

Final checks complete. About to write GPT data. THIS WILL OVERWRITE EXISTING
PARTITIONS!!
Do you want to proceed? (Y/N): Y
OK; writing new GUID partition table (GPT) to /dev/sda.
The operation has completed successfully.

J'utilise hbaituellement cron comme planificateur de taches. Il existe des implémentations de cron dans ArchLinux mais aucune d'entre elle n'est préinstallée. Par défaut le système utilise les systemd/Timers. Nous allons voir ici comment créer une tache de type systemd/Timers.
