A Dendritic Nix Flake

Regenerate flake and switch to it.

nix run .#write-flake
nix flake check
home-manager switch --flake .#desktop

nix flake show --all-systems

Layout

Everything under ./modules gets auto-imported by import-tree

Directory	Description
`hosts`	Provides either `homeConfigurations` or `nixosConfigurations`
`nix-tools`	Nix-specific tools, like factory functions for use in the flakes
`nixos`	`flake.modules.nixos`
`programs`	flakes that provide `flake.modules` attributes for specific programs
`services`	flakes that provide configuration for running services
`users`	flakes that provide configuration for individual users with the `flake.factory.user` factory

Mechanics

Flake

The top-level flake is created using flake-file

nix flake init -t github:vic/flake-file#default
...
nix run ".#write-flake"

This uses inputs.flake-parts.lib.mkFlake to create the flake.

The modules are automatically imported from the ./modules using import-tree.

Home Manager

Uses the home-manager module of flake-parts, which is imported in modules/home-manager/flake-parts.nix

Looks for options:

flake.homeConfigurations
flake.homeModules

Show exported home configurations:

nix eval --apply builtins.attrNames .#homeConfigurations

Testing

These commands would are useful for debugging

SYSTEM=lxc

# Just evaluate (fast, catches config errors)
nix eval .#nixosConfigurations.${SYSTEM}.config.system.build.toplevel

# Full build (slower, produces a bootable system)
nix build .#nixosConfigurations.${SYSTEM}.config.system.build.toplevel

Remote Deploy

nixos-rebuild switch --flake .#lxc --target-host root@fded:fb16:653e:25da:be24:11ff:fea0:753f
