Usage

Show what is provided:

nix flake show

Switch both system (NixOS) and home:

nix run .#nixos-switch

Switch home only:

nix run .#home-switch

Update all inputs:

nix flake update --commit-lock-file

Update a single input:

nix flake lock --update-input nixpkgs --commit-lock-file

Development

Use a local input during development:

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

Non-NixOS

Default shell

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

YubiKey ISO

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

Build the ISO:

nix build -L .#nixosConfigurations.yubikey-installer.config.system.build.isoImage

Copy the ISO to a USB-key/storage device:

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