• Download the latest Arch Linux ISO and copy it to a USB-drive.
• Connect the Up board to the network, a monitor and keyboard.
• Boot the Up Board, press F7 and select the USB-drive.
• Check if you received an IP-address over DHCP, else request one with dhclient.
• Install SSH to continue the installation over the network:

  pacman -Sy
  pacman -S openssh gpart
  passwd root
  systemctl start sshd
  
  # Connect to the Up board over SSH.
  ssh root@<IP-address>

• Determine the internal disk name with lsblk. In this case it is mmcblk0.
• Wipe signatures from drive:

  wipefs /dev/mmcblk0 -a

• Create partitions for EFI, root filesystem and swap.

  gdisk /dev/mmcblk0
  GPT fdisk (gdisk) version 1.0.1
  
  Partition table scan:
    MBR: not present
    BSD: not present
    APM: not present
    GPT: not present
  
  Creating new GPT entries.
  
  Command (? for help): 
  o	create a new empty GUID partition table (GPT)
  n, 512M, type EF00 (EFI)
  n, 2G, type 8200 (swap) 
  n, rest of disk, type 8300 (linux)

• Create the filesystems:

  mkfs.fat -F32 /dev/mmcblk0p1
  mkswap /dev/mmcblk0p2
  mkfs.ext4 /dev/mmcblkp3

• Mount the filesystems:

  swapon /dev/mmcblk0p2
  
  mount /dev/mmcblk0p3 /mnt       # Root filesystem
  mkdir /mnt/boot
  mount /dev/mmcblk0p1 /mnt/boot  # EFI filesystem mounted at /boot

• Install Arch Linux on the filesystems:

  pacstrap /mnt base

• Generate the fstab:

  genfstab -U /mnt >> /mnt/etc/fstab

• Enter the chroot:

  arch-chroot /mnt

• Configure the time zone

  ln -sf /usr/share/zoneinfo/Europe/Amsterdam /etc/localtime

• Set system time to hardware clock:

  hwclock --systohc

• Configure the locale:

  vi /etc/locale.gen
  locale-gen
  
  vi /etc/locale.conf
  LANG=en_US.UTF-8

• Set the hostname, archup in this example:

  vi /etc/hostname
  
  vi /etc/hosts
  127.0.1.1       archup.localdomain      archup

• Set the root password and create additional accounts:

  passwd root
  useradd ...

• Install packages on new filesystem:

  pacman -S intel-ucode openssh gpart

• Verify that efivars are available, ie booted in EFI-mode:

  ls /sys/firmware/efi/efivars

• Install EFI boot files:

  bootctl install

• Configure loader defaults:

  vi /boot/loader/loader.conf
  
  timeout 3
  default archlinux

• Add an Arch Linux entry:

  vi /boot/loader/entries/archlinux.conf
  
  title          archlinux
  linux          /vmlinuz-linux
  initrd         /intel-ucode.img
  initrd         /initramfs-linux.img
  options        root=PARTUUID="fcf051c4-9d53-48b1-96eb-3efbc23388ed" rw

• Exit the chroot and unmount the new filesystems:

  exit
  
  cd
  umount -R /mnt

• Boot from internal disk, remove USB-disk:

  reboot

• Configure SystemD networking:

  systemctl enable systemd-networkd
  systemctl start systemd-networkd
  
  systemctl enable systemd-resolved
  systemctl start systemd-resolved
  
  vi /etc/systemd/network/50-wired.network
  [Match]
  Name=enp1s0
  
  [Network]
  DHCP=ipv4
  
  # If you want an additional IP-address in case DHCP is not available.
  #[Address]
  #Label=enp1s0:0
  #Address=10.10.10.1/30
  
  
  rm /etc/resolv.conf
  ln -s /run/systemd/resolve/resolv.conf /etc/resolv.conf

• Start and enable SSHd:

  systemctl enable sshd
  systemctl start sshd

• Configure firewall scripts, for example ufw.
