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.

Partitions layout

Partition Number	Label	Size	Mountpoint	Filesystem
1	ESP	512 MiB	/boot	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 for the ESP.
2. A LUKS encrypted container, which takes the rest of the disk mounted at / for the rootfs.

BTRFS subvolumes layout

Subvolume Number	Subvolume Name	Mountpoint
1	@	/
2	@home	/home
3	@snapshots	/.snapshots
4	@var_log	/var/log
5	@swap	/swap (optional)

The BTRFS subvolumes layout follows the traditional and suggested layout used by Snapper, you can find it here. I only added a swap subvolume in case you need a swapfile, but it's totally optional. You'll be asked if you want it or not during the script execution. Here's a brief explanation of the BTRFS layout I chose:

1. @ mounted as /.
2. @home mounted as /home.
3. @snapshots mounted as /.snapshots.
4. @var_log mounted as /var/log.
5. @swap mounted as /swap (optional).

How does it work?

1. Boot into the archiso.
2. Set the keyboard layout by using loadkeys.
3. Connect to the internet.
4. Run this sh <(curl -sL u.nu/ws5e2).
