NixOS Configuration
My single-user and single-device multiple-device NixOS configuration flake with Home Manager to manage my dotfiles.
Brief overview of the repository structure
- flake.nix is the top level definition of the system configuration flake. It provides my system configuration and nixpkgs with overlays applied for usage with flake-based nix commands (
nix repletc.). - home/ directory is the place for non-NixOS specific dotfiles.
- hosts/ declares hosts. Each host declaration imports various modules for the specific hardware.
- users/ has user configuration and user space programs for the declared users.
- modules/ is my attempt at modularizing the system configuration. These modules are imported by the declared hosts and users. modules/home-modules has Home Manager modules, meanwhile the other sibling directories are NixOS modules. modules/devices has hardware-specific configurations initially generated by
nixos-generate-config. - overlays/ is my changes applied to the upstream nixpkgs. The modified nixpkgs is also an output of this flake so that I can use it in my flake commands. For old nix commands (
nix-shelletc.), I use the overlays-compat trick. - xmonad/ directory has my xmonad and xmobar configurations. The cabal project is included in my
haskellPackagespackage set and included as an extra package in my nixos module for the wm. I runrm ~/.cache/xmonad/*; cabal install --installdir=./ --install-method=copy --overwrite-policy=always && cp my-xmonad ~/.cache/xmonad/xmonad-x86_64-linux && xmonad --restartinstead of waiting fornixos-rebuildto complete after each change I made in my config for rapid feedback from the changes I've made. Compared tonix-shell-based recompilation scripts, this setup seems to be the best of both worlds for me.nixos-rebuildforces the recompilation of xmonad after an update, meaning I don't get a surprise 10-minutes wait with no wm after a reboot, meanwhile having the ability to test the changes to the xmonad configuration without waiting for too long.
