Nix Dotfiles

These are my dotfiles for several nix machines. Here are some of the interesting files and dirs:

Path	Purpose
/home	home-manager configuration.
/hosts	Machine specific NixOS configurations.
/hosts/common.nix	Configuration that is equal for all hosts.
/lib	Custom lib functions that has not been upstreamed (or should not be) to nixpkgs. I'm trying to phase these out as much as possible.
/modules	Custom nixos modules that I use in my own configuration. If you see options that does not appear in NixOS Search, they might be defined here.
/package-overrides	Updated or pinned versions of packages that have not been upstreamed to nixpkgs (yet).
/secrets	Encrypted sops-nix secrets.
flake.nix	The root of everyting. Defines the inputs and outputs of the project. Also applies misc overlays and adds config-wide modules. See Nix Flakes for more information.

Hosts

Host	Machine type	Purpose
Tsuki	Dell Poweredge r710 server	Data storage / Build server / Selfhosted services. This server hosts a wide variety of services, including websites, matrix server, git repos, CI/CD and more. This is probably the most interesting machine to pick config from
Kasei	AMD Zen 2 CPU / Nvidia GPU - desktop computer	Semi-daily driver. This is my main computer at home. Most of the configuration written in /home is made specifically for this computer, since Eisei is out of service at the moment.
Eisei	HP Laptop	At the moment, this laptop is not in use. I've found that I'm not able to use NixOS quickly enough in a university environment where I need to rapidly install software and maintain project configurations (Makefile, Maven, django, npm, etc...) for several subjects. In addition to the configurations, some of the software is not available on NixOS. As a result, I would the be forced to package or FHS a lot of stuff in order to do anything productive. I might return to using NixOS on my laptop in the future.

home-manager configuration

Path	Purpose
/home/config	Configuration for everything that is not a program, nor a service, and are big enough to warrant their own file or directory.
/home/modules	Custom home-manager modules.
/home/packages.nix	A list of packages that should be included in the environment.
/home/programs	Configuration for programs that have their own home-manager modules.
/home/services	Configuration for services/daemons that are user-specific.
/home/shell.nix	Shell-agnostic configuration. This includes aliases, envvars, functions, etc.
