ie. using our free partition number 3 formatted with a 6 GB Ext4 file system

Partitioning

```
fdisk /dev/sda
```

n 3 [enter] +6G

Formatting

mkfs.ext4 -E discard -L DEBIAN /dev/sda3

```
mount /dev/disk/by-label/DEBIAN /mnt
```

Requirements

```
pacman -S abs
```
```
pacman -S base-devel
```
```
abs
```
```
mkdir /tmp/debootstrap
```
```
cd /tmp/debootstrap
```
