/etc/nixos to configure my NixOS hosts.

Run ./init.py after cloning to initialize the repository and/or generate new configuration files.

Typically, this repository will live at ~/nix-config, and /etc/nixos will be a clone of that (sudo git clone ~/nix-config/ /etc/nixos).

configuration.nix is a symlink to hosts/$HOSTNAME.nix, which in turn imports hosts/$HOSTNAME-hardware-configuration.nix.

init.py will generate that symlink and configuration file if it doesn't already exist.

The hosts/ directory contains $HOSTNAME.nix and $HOSTNAME-hardware-configuration.nix for each host.

$HOSTNAME.nix contains configuration for specific machines that aren't shared.

Configuration sets that may be shared between machines to enable/disable specific features.

Most notable is imports/packages.nix, which lists packages to be installed.

Resources for configuration; may include hashed passwords (hopefully .gitignore'd!), SSH keys, that kind of thing.

Extra NixOS modules.

Patterns for using nixpkgs on machines without NixOS installed, such as Pop!_OS or MacOS.

Scripts / files for generating bootable copy-on-write disk images for QEMU.

nixpkgs overlays; overlays/all.nix is a list of all overlays and overlays/default.nix is an attrset of overlays.

A nixpkgs-like repository (in the sense of a package repository, not a git repository) using the inputs and [callPackage] design patterns. rebeccapkgs contains various packages and derivations not in nixpkgs.
