This is my NixOS configuration repository.
It contains system and user configuration files. System files in system are used to build NixOS machine configurations and thus managing the state of the whole operating system.
Home files in home are used to configure user applications and dotfiles managed by home-manager, which is installed either by system or manually on non-nixos platforms.
More info on nixos website.
Old readme can be found here.
To install NixOS on a machine, follow the steps in the nixos manual.
To install NIX on non-NixOS system (Linux), follow the steps in the nix manual.
If you have NIX installed on your Linux distro, you can install and use home-manager to manage packages and configurations (dotfiles) for user session. This way you can have the same set of user config files for NixOS and non-NixOS systems (reproducible environment).
Follow the steps in home-manager manual.
For maintenance of both system and home I created two scripts, each installed by their manager: nixos-update and home-update.
Both scripts build the derivation, show the diff and ask for confirmation. System update requires sudo.
Both scripts also accept option -r, which updates the flake lock file and thus does a system update instead of just rebuild.
Other flags and options are passed on to the nix build command, excluding -r if present.
You can read more on each script in the docs for NixOS and home-manager.
I found it on internet some time ago, but it was bad quality. I turned it into vector image and exported 1080p and 1440p variants. If you find the author please thank him/her in my name.
