archlinux-installer-script

This installer script is meant to be used from a bootable usb when you install Arch Linux. This script tries to only do what is necessary to get up and running with an Arch console on your machine. The script is configured for EFI only, but you can change two lines to turn it into a BIOS install (disk formatting and grub installation). Refer to the arch install guide so that you know what you're doing.

The script does the following setup:

• Partition drive in order: 512MiB Boot, 14G Swap, 50G Root, Home (remainder).
• Format partitions.
• Mount partitions to /mnt.
• Create directories on /mnt.
• Call pacstrap on /mnt to install the following packages:
  • Core linux linux-firmware base base-devel efibootmgr grub
  • System vim git man networkmanager
• Generate fstab in /mnt/etc/fstab.
• arch-chroot to the installation and do the following:
  • Generate locale for en_US.UTF-8.
  • Set timezone to Europe/Amsterdam (change later).
  • Synchronize time with hwclock --systohc.
  • Enable networkmanager with systemd.
  • Set root password to 123 (change later).
  • Set hostname to archer.
  • Create /boot/grub directory.
  • Create Grub config with grub-mkconfig.
  • Install Grub with grub-install.
• Outside of chroot: unmount and notify user of completion.

Install guide

To get internet you need to use the iwctl wifi manager or plug in ethernet cable.

iwctl
[iwd]# device list
[iwd]# station <DEVICE> scan
[iwd]# station <DEVICE> get-networks
[iwd]# station <DEVICE> connect <SSID>

When you have internet you can download the script with curl:

curl -LO "https://raw.githubusercontent.com/parcevval/archlinux-installer-script/master/archstrap.sh"

Once you have the script you can run it. Arguments for the command are automatically printed. If arguments are incorrect, the script will tell you. Be sure that you want to wipe your drive and type y to proceed.

chmod +x archstrap.sh
./archstrap.sh /dev/sda
Are you certain? (y/n)
y
...

At the end you will be greeted with a message giving you the root login credentials: username root and 123 as password. Change these later.
