Installation from Arch ISO

Connect to internet via Ethernet cable.

loadkeys fi
archinstall

Boot into desktop, then

# Run .install.sh in a child shell on a live USB environment.
bash <(curl -fsSL https://eniemela.fi/api-v1/laptop-install.sh)

If the Chaotic-AUR CDN returns HTTP 503, replace it with the geo mirror and rerun the installer:

sed -i 's|https://cdn-mirror\.chaotic\.cx|https://geo-mirror.chaotic.cx|g' .install.sh

Test the installer with QEMU

Install QEMU on Arch Linux:

sudo pacman -S --needed qemu-desktop

From the repository root, download the latest Arch ISO and create a sparse 64 GiB test disk:

mkdir -p .vm

curl -L \
  https://geo.mirror.pkgbuild.com/iso/latest/archlinux-x86_64.iso \
  -o .vm/archlinux-x86_64.iso

curl -L \
  https://geo.mirror.pkgbuild.com/iso/latest/sha256sums.txt \
  -o .vm/sha256sums.txt

(
  cd .vm
  sha256sum --check --ignore-missing sha256sums.txt
)

qemu-img create -f qcow2 ".vm/dotfiles.qcow2" 64G

The image is sparse, so it initially consumes little physical disk space. Start the VM:

qemu-system-x86_64 \
  -machine q35,accel=kvm \
  -cpu host \
  -m 8G \
  -smp 4 \
  -device virtio-vga \
  -display gtk \
  -nic user,model=virtio-net-pci \
  -drive file=".vm/dotfiles.qcow2",if=virtio,format=qcow2 \
  -cdrom ".vm/archlinux-x86_64.iso" \
  -boot once=d

Inside the Arch ISO, run the installer:

loadkeys fi
archinstall

Select /dev/vda as the target disk. It is the disposable virtual disk, not a physical drive. When installation finishes, reboot:

reboot

Because QEMU uses -boot once=d, the VM should boot from the installed virtual disk after reboot.

Boot the installed virtual system

Immediately after installation, reboot should boot the installed disk because the installer VM uses -boot once=d. To open it again later, run this from the repository root.

qemu-system-x86_64 \
  -machine q35,accel=kvm \
  -cpu host \
  -m 8G \
  -smp 4 \
  -device virtio-vga \
  -display gtk,clipboard=on \
  -device virtio-serial-pci \
  -chardev qemu-vdagent,id=vdagent,name=vdagent,clipboard=on \
  -device virtserialport,chardev=vdagent,name=com.redhat.spice.0 \
  -nic user,model=virtio-net-pci \
  -drive file="$PWD/.vm/dotfiles.qcow2",if=virtio,format=qcow2

Enable the host--guest clipboard

Install and start the clipboard agent once inside the virtual system.

sudo pacman -Syu spice-vdagent
sudo systemctl enable --now spice-vdagentd.socket
sudo reboot
