It enables a consistent experience and computing environment across all of my machines. This project is written with [[https://gnu.org/software/emacs/][GNU/Emacs]], leveraging its capabilities for [[https://doi.org/10.1093/comjnl/27.2.97][Literate Programming]], a technique where programs are written in a natural language, such as English, interspersed with snippets of code to describe a software project. #+NAME: file-warning #+BEGIN_SRC text This file is controlled by /etc/dotfiles/README.org #+END_SRC ** Getting Started 1) [[https://nixos.org/download.html][Download the latest version of NixOS]] 2) [[https://nixos.org/manual/nixos/stable/#sec-installation-partitioning][Partition your drives and mount the file system]] 3) Clone the project ~git clone git@git.chrishayward.xyz:chris/dotfiles /mnt/etc/dotfiles~ 4) Load the default shell ~nix develop /mnt/etc/dotfiles~ 5) Install the system ~sudo nixos-install --impure --flake /mnt/etc/dotfiles#nixos~ 6) Reboot, login and start a graphical system ~startx~ ** Making Changes The ~nixos-rebuild~ command updates the system so that it corresponds to the configuration specified in the module. It builds the new system in =/nix/store/=, runs the activation scripts, and restarts and system services (if needed). The command has one required argument, which specifies the desired operation: #+NAME: rebuild-command-table | Command | Description | |----------+---------------------------------------------------------------------------------| | boot | Build the new configuration and make it the boot default, without activation | | test | Build and activate the new configuration, without adding it to the boot menu | | switch | Build and activate the new configuration, making it the new boot default | | build | Build the new configuration, without activation, nor adding it to the boot menu | | build-vm | Build a script that starts a virtual machine with the desired configuration | After making changes to the configuration the ~switch~ command will build and activate a new configuration. #+BEGIN_SRC shell # Build and activate a new configuration. sudo nixos-rebuild switch --flake $FLAKE#$HOSTNAME #+END_SRC Instead of building a new configuration, it's possible to rollback to a previous generation using the ~nixos-rebuild~ command, by supplying the ~--rollback~ argument. #+BEGIN_SRC shell # Rollback to the previous generation. sudo nixos-rebuild switch --rollback #+END_SRC ** Docker Container It's possible to use parts of this configuration using a [[https://docker.org][Docker]] container. By default, sandboxing is turned /off/ inside of the container, even though it's enabled in new installations. This can lead to differences between derivations built inside containers, versus those built without any containerization. This is especially true if a derivation relies on sandboxing to block sideloading of dependencies. Install from the command line: ~docker pull ghcr.io/chayward1/dotfiles:main~ #+BEGIN_SRC dockerfile :tangle Dockerfile :noweb yes # <> # Derive from the official image.

It uses a declarative configuration language to define entire computer systems, and allows reliable system upgrades and rollbacks. [[https://nixos.org][NixOS]] also has tool dedicated to DevOps and deployment tasks, and makes it trivial to share development environments. #+BEGIN_SRC nix :noweb yes :tangle flake.nix # <> { description = "<>"; inputs = { <> <> <> <> <> }; outputs = inputs @ { self, nixpkgs, nixpkgs-unstable, ... }: { <> } // <> } #+END_SRC ** Nixpkgs [[https://nixos.org/manual/nixpkgs/stable][Nixpkgs]] is a collection of over 60,000 software packages that can be installed with the [[https://nixos.org/manual/nix/stable/Nix][Nix Package Manager]].

It's an experimental replacement for the ~nix-shell~ command that is compliant with Nix Flakes. It provides an interactive build environment nearly identical to what Nix would use to build /installable/.

Flakes are the unit for packaging Nix code in a reproducible and discoverable way. They can have dependencies on other flakes, making it possible to have multi-repository Nix projects. A flake is a filesystem tree that contains a file named =flake.nix=. It specifies some metadata about the flake such as dependencies (inputs), as well as the values such as packages or modules (outputs).
