NixOS Dotfiles

NixOS + Home Manager configs for my machines, composed with den

git clone https://github.com/eldios/dotfiles ~/dotfiles
cd ~/dotfiles
sudo nixos-rebuild switch --flake .#$(hostname)

Once the config is active, the nixu alias does the same through nh os switch (built as the regular user, activated with sudo).

Any path starting with _ is skipped by the module loader and holds plain NixOS or Home Manager modules, imported by the aspect or host next to it.

A host is a list of aspects. An aspect bundles the NixOS and Home Manager halves of one feature: den.aspects.neovim carries the system editor in its nixos class and the LazyVim setup in its homeManager class, and a host that includes it gets both. Users are aspects as well: modules/users/eldios.nix includes den's define-user, primary-user and user-shell batteries for the account itself, and host-aspects, which hands the user the Home Manager half of every aspect the host includes. Configuration that belongs to one user on one host goes through provides.<user>.homeManager in the host's aspect.

Secrets come from a private repo through the secrets flake input, consumed by sops-nix; there is no secrets/ directory here.
