Using Nix from AUR on Arch Linux

nix-example.sh

#!/bin/sh

## Or use an AUR helper, e.g.
## sudo aura -A nix
sudo pacman -S base-devel git
git clone https://aur.archlinux.org/nix.git
cd nix
makepkg -s
sudo pacman -U nix-*.pkg.tar.xz

sudo groupadd -r nixbld
for n in $(seq 1 10); do sudo useradd -c "Nix build user $n" \
    -d /var/empty -g nixbld -G nixbld -M -N -r -s "$(which nologin)" \
    nixbld$n; done

. /etc/profile.d/nix.sh
sudo nix-daemon & disown
export NIX_REMOTE=daemon

## This is probably not ideal.
mkdir -p /nix/var/nix/profiles
sudo chown $(id -u):$(id -g) /nix/var/nix/profiles
