## Arch Linux recipe

### Keyboard

If the keyboard is not American layout, load the target keyboard layout by
running the following command:

```bash
loadkeys br-abnt2
```

### Internet

Make sure you are connected to internet and your PC has a configured IP.

```bash
ip addr show
# or
wifi-menu
ping google.com
```

### Partitioning

Check the available storage units and do the partitioning.

```bash
fdisk -l
cfdisk /dev/nvme0n1
```

Create the following partitions:

| Partition | Location       | Size | Type             |
| --------- | -------------- | ---- | ---------------- |
| Boot      | /dev/nvme0n1p1 | 512M | BIOS Boot        |
| /         | /dev/nvme0n1p2 | 25G  | Linux Filesystem |
| /home     | /dev/nvme0n1p3 | \*   | Linux Filesystem |

Check if the partitions were created:

```bash
fdisk -l /dev/nvme0n1
```

### Formatting and making the filesystems

Run the following commands to format the partitions:

```bash
mkfs.vfat -F32 -n EFI /dev/nvme0n1p1
mkfs.ext4 /dev/nvme0n1p2
mkfs.ext4 /dev/nvme0n1p3
```

And then mount them:

```bash
mount /dev/nvme0n1p2 /mnt
mkdir /mnt/boot
mkdir /mnt/boot/EFI
mount /dev/nvme0n1p1 /mnt/boot
mkdir /mnt/home
mount /dev/nvme0n1p3 /mnt/home
ls /mnt
```

### Base install

Run the following commands to install the base:

```bash
pacstrap /mnt base base-devel
```

### Create fstab

Run the following command to generate the `fstab` file.

```bash
genfstab -U -p /mnt >> /mnt/etc/fstab
cat /mnt/etc/fstab
```

Make sure your `fstab` file has all previously created partitions.

### Go to the new system

```bash
arch-chroot /mnt
```

### Sync time

Run the following command:

```bash
ln -s /usr/share/zoneinfo/America/Sao_Paulo /etc/timezone
hwclock --systohc
```

## Locale

Uncomment `en_US.UTF-8 UTF-8` and other needed locales in `/etc/locale.gen`, and generate them with:

```bash
locale-gen
```

### Creating the user

Define your root user password:

```bash
passwd
```

And run the following command to create your user:

```bash
useradd -m -G wheel -s /bin/bash YOUR_USER_NAME
ls /home/
```

Use the following command to set the user password if needed:

```bash
passwd YOUR_USER_NAME
```

Install some useful programs, including `sudo` and add that user to `sudoers`:

```bash
pacman -S dosfstools os-prober mtools network-manager-applet \
          networkmanager wpa_supplicant wireless_tools dialog sudo

nano /etc/sudoers
```

Add `YOUR_USER_NAME ALL=(ALL) ALL` in the and of `sudoers` file.

### Configure localhost

Run the following commands to define your hostname:

```bash
echo YOUR_USER_NAME > /etc/hostname
cat /etc/hostname
```

Edit and add following to `hosts`:

```
127.0.0.1  localhost.localdomain  localhost
::1  localhost.localdomain  localhost
127.0.1.1  YOUR_USER_NAME.localdomain  YOUR_USER_NAME
```

To:

```bash
nano /etc/hosts
```

## Install linux-zen

Run the following commands:

```bash
pacman -S linux-zen linux-zen-headers
mkinitcpio -p linux-zen
uname -r
```

### Install Grub

Run the following commands to setup Grub using UEFI:

```bash
pacman -S grub-efi-x86_64 efibootmgr os-prober
os-prober
grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id=Arch --recheck
grub-mkconfig -o /boot/grub/grub.cfg
mkdir /boot/grub/locale
cp /usr/share/locale/en\@quot/LC_MESSAGES/grub.mo /boot/grub/locale/en.mo
```
