Install Arch Linux on Macbook Air 2015

arch.txt

1 -> Download and Write
  Download latest "archlinux.iso" from "archlinux.org"
  $ dd if={archlinux.iso} of=/dev/sd{x} bs=1M status=progress
  "/dev/sd{x}" = USB drive

2 -> IF NOT ARCH FOR BUILDING OFFLINE REPOSITORY
  Install "virtualbox"
  Run until step 8 and then go back to step 3

3 -> Partitioning
  $ cgdisk /dev/sda
  New partition: 512M EFI System (EF00)
  New partition: Linux Filesystem (8300)

4 -> Format
  $ mkfs.fat -F 32 /dev/sda1
  $ mkfs.ext4 /dev/sda2

5 -> Mount
  $ mount /dev/sda2 /mnt
  $ mkdir /mnt/boot
  $ mount /dev/sda1 /mnt/boot

6 -> Copy offline repository
  $ mkdir /hard
  $ mount /dev/sd{x}1 /hard
  $ cp -r /hard/pkg /mnt/
  $ cd /mnt/pkg
  $ repo-add pkg.db.tar.gz *.zst *.xz
  $ cd

7 -> Modify pacman configuration for using offline repository
  $ nano /etc/pacman.conf
  Comment out (Add #) All repositories
  Add:
	[pkg]
  	SigLevel = Never
  	Server = file:///mnt/pkg

8 -> Install operating system
  $ pacman -Sy
  $ pacstrap -i /mnt base base-devel linux-headers dkms \
    	     	     broadcom-wl-dkms linux linux-firmware \
		     networkmanager nano
  "pacstrap" command will download packages and their dependencies to
  "/mnt/var/cache/pacman/pkg". We can use these packages for building
  an offline repository:
  $ mkdir /hard
  $ mount /dev/sd{x}1 /hard
  $ rm -r /hard/pkg
  $ cp -r /mnt/var/cache/pacman/pkg /hard
  $ umount /hard
  If we just wanted the repository then exit this installation and
  reboot to new installation using usb.

9 -> Generating "fstab"
  $ genfstab -U /mnt >> /mnt/etc/fstab

10 -> Switch to new system
  $ arch-chroot /mnt

11 -> Locale configuration
  $ nano /etc/locale.gen
  Use [C-w] for search
  Uncomment "en_US.UTF-8"
  Save and exit: [C-o], Enter, [C-x]
  $ locale-gen
  $ echo LANG=en_US.UTF-8 > /etc/locale.conf
  $ export LANG=en_US.UTF-8

12 -> Hostname
  $ echo {Hostname} > /etc/hostname

13 -> Password and Users
  $ passwd  # Specify password for "root" user
  $ useradd -m -g root -G wheel -s /bin/bash {username}
  "-m" for making home directory
  $ passwd {username}

14 -> Sudo
  $ EDITOR=nano visudo
  Search for ([C-w]) "%wheel". Uncomment the line below "## Same thing
  without a password"

15 -> Boot loader
  $ bootctl --path=/boot install
  $ blkid -s PARTUUID -o value /dev/sda2 > \
    	  /boot/loader/entries/arch.conf
  "/dev/sda2" = root partition
  $ nano /boot/loader/entries/arch.conf
  File content:
       title	Arch
       linux	/vmlinuz-linux
       initrd	/initramfs-linux.img
       options	root=PARTUUID={The current content of the file} rw
