== Installation ==

See [[https://wiki.archlinux.org/title/installation_guide|the manual]].

But roughly...

 * Download an ISO and flash to a USB
   * try: `dd bs=4M if=path/to/archlinux-version-x86_64.iso of=/dev/sdXN conv=fsync oflag=direct status=progress`
 * Boot into the live USB
 * [[Linux/PartitionTables|Partition]] and [[Linux/FileSystems|format]] the installation drive with
   * an '''EFI System Partition''' ('''ESP''') with ~512K formatted as FAT32
     * sometimes this partition type is labeled ''EFI (FAT-12/16/32)''
   * a [[Linux/Swap|swap partition]]
   * a '''root partition''' formatted as ext4
     * leave as the default (''Linux'') partition type
 * `mount(8)` the root partition to `/mnt`, and then the ESP to `/mnt/boot`
 * `swapon(8)` the swap partition
 * install the kernel
   * try: `pacstrap -K /mnt base linux linux-firmware`
 * generate the [[Linux/FsTab|fstab(5)]] file
   * try: `genfstab -U /mnt >> /mnt/etc/fstab`
 * `chroot(1)` into the new installation
   * try: `arch-chroot /mnt`
 * install `grub` and any microcode that may be needed
 * setup the boot loader
   * try: `grub-install --target=x86_64-efi --efi-directory=/mnt/boot` --bootloader-id=GRUB` then `grub-mkconfig -o /boot/grub/grub.cfg`
 * if needed, install and setup [[Linux/Networking|networking]] (because the live USB includes some daemons and utilities that aren't installed and enabled by default)
 * `poweroff(8)`, remove the live USB, and try booting directly into the new installation



=== Upgrading ===

Arch Linux is a '''rolling release'''. There are no versioned releases, just the current state.

Keep an installation of Arch Linux up-to-date by frequently running:

{{{
sudo pacman -Syyu
}}}
