Introduction

easy-arch is a script made in order to boostrap a basic Arch Linux environment with snapshots and encryption by using a fully automated process (UEFI only).

How does it work?

  1. Download an Arch Linux ISO from here
  2. Flash the ISO onto an USB Flash Drive.
  3. Boot the live environment.
  4. Set the keyboard layout by using loadkeys.
  5. Connect to the internet.
  6. Run this bash <(curl -sL git.io/JtRu2).

Partitions layout

Partition Number Label Size Mountpoint Filesystem
1 ESP 512 MiB /boot/efi FAT32
2 Cryptroot Rest of the disk / BTRFS Encrypted (LUKS)

The partitions layout is pretty straightforward, it's inspired by this section of the Arch Wiki. As you can see there's just a couple of partitions:

  1. A FAT32, 512MiB sized, mounted at /boot/efi for the ESP.
  2. A LUKS encrypted container, which takes the rest of the disk space, mounted at / for the rootfs.

BTRFS subvolumes layout

Subvolume Number Subvolume Name Mountpoint
1 @ /
2 @boot /boot
3 @home /home
4 @snapshots /.snapshots
5 @var_log /var/log

The BTRFS subvolumes layout follows the traditional and suggested layout used by Snapper, you can find it here. Here's a brief explanation of the BTRFS layout I chose:

  1. @ mounted as /.
  2. @boot mounted as /boot.
  3. @home mounted as /home.
  4. @snapshots mounted as /.snapshots.
  5. @var_log mounted as /var/log.
