nix run nixpkgs#nixos-rebuild -- switch --flake .

Switch home only:

nix run home-manager -- switch --flake .

Update all inputs:

nix flake update

Update a single input:

nix flake lock --update-input nixpkgs

Use a local input during development:

nix flake lock --override-input nixpkgs path:../nixpkgs

If you use a custom shell, you need to manually set the default shell, this is done by:

echo $HOME/.nix-profile/bin/fish | sudo tee -a /etc/shells
chsh -s $HOME/.nix-profile/bin/fish

Used to create a safe environment for YubiKey operations having all the necessary tools.

Build the ISO:

sudo dd if=result/iso/*.iso of=/dev/sda status=progress
sync
