To update flake dependencies: nix flake update

To rebuild the flake for home-desktop: nixos-rebuild switch --flake .#home-desktop --sudo

To do both: nix flake update && nixos-rebuild switch --flake .#home-desktop --sudo

Fresh Install

Run: nixos-rebuild switch --flake github:blakespiers/nix-config#HOST --sudo

Reboot and repeat the rebuild step.

Cleanup

Delete all old generations: nix-collect-garbage -d

Delete generations older than 10 days: nix-collect-garbage -d --delete-older-than 10d

Alternatively, use the nh command from nixpkgs for more control: nh clean all --keep 3
