### Introduction ### Introduction
[easy-arch](https://github.com/classy-giraffe/easy-arch) is a **bash script** made in order to install **Arch Linux** and configure it with proper settings (while keeping it vanilla): [easy-arch](https://github.com/classy-giraffe/easy-arch) is a **bash script** that boostraps **Arch Linux** and configures it:

### Partitions layout ### Partitions layout
The **partitions layout** is simple and it consists of only two partitions:
1. A **FAT32** partition (512MiB), mounted at `/boot/` as ESP.
2. A **LUKS2 encrypted container**, which takes the rest of the disk space, mounted at `/` as root.
| Partition Number | Label | Size | Mountpoint | Filesystem | | Partition Number | Label | Size | Mountpoint | Filesystem |
|------------------|-----------|-------------------|----------------|-------------------------| |------------------|-----------|-------------------|----------------|-------------------------|
| 1 | ESP | 512 MiB | /boot/ | FAT32 | | 1 | ESP | 512 MiB | /boot/ | FAT32 |
| 2 | Cryptroot | Rest of the disk | / | BTRFS Encrypted (LUKS2) | | 2 | Cryptroot | Rest of the disk | / | BTRFS Encrypted (LUKS2) |
The **partitions layout** is simple and it's inspired by [this section](https://wiki.archlinux.org/index.php/Dm-crypt/Encrypting_an_entire_system#Btrfs_subvolumes_with_swap) of the Arch Linux Wiki. As you can see there're only two partitions:
1. A **FAT32**, 512MiB sized, mounted at `/boot/` for the ESP.
2. A **LUKS2 encrypted container**, which takes the rest of the disk space, mounted at `/` for the rootfs.
### BTRFS subvolumes layout ### BTRFS subvolumes layout
The **BTRFS subvolumes layout** follows the traditional and suggested layout used by **Snapper**, you can find it [here](https://wiki.archlinux.org/index.php/Snapper#Suggested_filesystem_layout).

The **BTRFS subvolumes layout** follows the traditional and suggested layout used by **Snapper**, you can find it [here](https://wiki.archlinux.org/index.php/Snapper#Suggested_filesystem_layout). Here's a brief explanation of the **BTRFS layout** I chose:
1. `@` mounted at `/`
2. `@home` mounted at `/home`
3. `@root` mounted at `/root`
4. `@srv` mounted at `/srv`
5. `@snapshots` mounted at `/.snapshots`
