Installation

Caution

Applying custom configurations, especially those related to your operating system, can have unexpected consequences and may interfere with your system's normal behavior. While I have tested these configurations on my own setup, there is no guarantee that they will work flawlessly for you. I am not responsible for any issues that may arise from using this configuration.

# Automatic installation (Live CD)
nix-shell -p curl git
./install.sh

# Manual installation (Live CD)
nix-shell -p curl git
curl https://raw.githubusercontent.com/shuritch/nixos/main/core/cluster/<hostname>/disko.nix > /mnt/config/disko.nix
# Edit disko.nix (Replace device with name from lsblk result at least)
sudo nix --experimental-features "nix-command flakes" run github:nix-community/disko -- --mode disko /mnt/config/disko.nix
git clone https://github.com/shuritch/nixos /mnt/etc/nixos/flake
sudo nixos-generate-config --dir /mnt/etc/nixos
mv -f /mnt/etc/nixos/hardware-configuration.nix /mnt/etx/nixos/flake/cluster/<hostname>
sudo nixos-install --flake /mnt/etc/nixos/flake#<hostname>
# reboot 🚀

Updates

nix flake update
sudo nixos-rebuild --upgrade switch --flake .#<hostname>

Rebuilding

git add . # Important if new files were created
sudo nixos-rebuild switch --flake .#<hostname> # If Hosts updated
