Arch install with encrypted BTRFS (LUKS2), GRUB e AwesomeWM

My notes with the steps to install Arch Linux with encrypted BTRFS (LUKS2) and GRUB.

If you stumbled upon this document looking for a guide to install Arch Linux, I recommend checking the official installation guide on the Arch Linux Wiki: https://wiki.archlinux.org/title/Installation_guide. This is not a guide, just some notes that I'm taking while trying this setup and getting fragments of information from the internet.

Pre-Requisites

This guide will use the winget CLI tool to install and configure Oh-My-Posh. If you haven't already, I suggest installing Windows Terminal from the Microsoft Store and use Oh-My-Posh with it. If you'd rather not use Windows Terminal for some reason, you can still use Oh-My-Posh with PowerShell. Whichever you choose, check out these instructions to install winget.

Install Oh-My-Posh

winget install JanDeDobbeleer.OhMyPosh -s winget
