Nora's Configs

The evolution of nora/dotfiles; Nix configs under home-manager deployed with morph.

Deployment Host

On the depoyment host, I use nix channels, and set:

$ nix-channel --list
home-manager https://github.com/nix-community/home-manager/archive/release-22.11.tar.gz
nixpkgs https://nixos.org/channels/nixos-22.11

Layout

These files are "organized" as follows:

• common/ is the directory where most of the configuration happens. These are the files used in more than one host configuration, now or later.
  • home_manager/ includes all common home-manager configs.
    • fragments/ contains package and configuration sets for specific use cases For example, home_manager/rust.nix includes packages and options related to Rust development.
    • common.nix contains all configurations common across all home-manager deployments. For example, GPG agent configurations and Vim settings.
  • users/ contains basic user definitions.
  • default.nix is the core file defining the default nix configuration for all machines.
  • common.nix contains all the common NixOS definitions that all machines will need.
  • fragments/ contains small functions for configuring particular services or system aspects, like Syncthing
• files/ contains files used by home-manager to deploy anything not covered by existing home-manager options.
• hosts/ defines host-specific configurations for NixOS and home-manager.
  • felonyspork/ is the bastion/external server (Lenovo Tiny)
    • configuration.nix is the core NixOS configuration file, copied from the installed system
    • hardware-configuration.nix is the hardware config, imported in configuration.nix.
    • home.nix is the home-manager config specifically for felonyspork.
• ops/ contains all the information needed to deploy using morph.

The import structure goes as follows:

• The ops/<network>/network.nix file defining the hosts in a network imports
  • common/default.nix for all-machine defaults, which imports
    • common/common.nix for common setup, including fonts, nixpkgs setup, and locale, which imports
      • common/users/* which sets up usernames, shells, SSH keys, and groups for users.
  • the host's hosts/<host>/configuration.nix file, which configures NixOS on the host and imports
    • appropriate common/fragments/<fragment>.nix files, for specific services or use cases.
    • the hosts's hosts/<host>/hardware-configuration.nix file, which configures partitions and drivers.
  • the host's hosts/<host>/home.nix file, which configures home-manager for that host, by importing
    • common/home_manager/common.nix, which configures home-manager for all machines
    • various common/home_manager/fragments/<fragment>.nix, which configures a specific use case, like graphical programs or Rust development.

Unconfigured

Currently, the primary dependencies are:

• DNS that sets the crimespoon and felonyspork names
• Mullvad VPN config on crimespoon, allowing LAN connections

Deployment

Simply run push:

$ ops/home/push

To push to only a single machine, use ops/home/push --on <machine>.
