nixfiles

These are the NixOS configurations for my systems. I run nothing other than NixOS on my hardware, aside from virtual machines.

Nodes

Node	Purpose
athame	Currently the main server. Ad-hoc hetzner cloud box.

hardware	Sub-profiles for my hardware are provided here. Some are reusable.

User Profiles

Profile	Purpose
base	base16, git, inputrc, packages, pass, rink, secrets, SSH, tmux, weechat, vim, xdg and zsh configuration.

CI

CI for this repository uses arcnmx/ci and aims to achieve two goals:

Action	Purpose
nodes	Build and cache host closures, show state of host evaluability/buildability.
niv-cron	Automatically update the dependencies used by the repository, cache them and host closure build results with them.

Dependencies

Dependency	Reasoning
nmattia/niv	Dependency management. Will move to flakes when stable.
nix-community/home-manager	home-manager. Self-explanatory.
nix-community/NUR	Firefox extensions and such.
arcnmx/tf-nix	The deploy system used, also provides DNS, secrets and node provisioning. (Anything terraform can do.)
arcnmx/ci	The CI integration system used.
arcnmx/nixexprs	Packages and modules I heavily make use of.
nix-community/impermanence	Impermanence! Erase your darlings.
kittywitch/anicca	A helper for moving to impermanence.
kittywitch/nixexprs	Packages and modules I have made.
nixos-mailserver	The mail server module I use.
hexchen/nixfiles	Yggdrasil module. Yggdrasil nodes.
nix-community/emacs-overlay	An overlay for emacs versions. Currently unused.
vlaci/nix-doom-emacs	Nixified DOOM emacs. Currently unused.

Commands

The commands here aside from the nix build command are provided through the shell. The <target> and <host> commands are runners provided through arcnmx/tf-nix.

Please use nix-shell or direnv/direnv. The shell is not compatible with nix-community/nix-direnv.

Command	Purpose
`nf-update`	Fancier `niv update`.
`nf-actions`	Updates CI integrations.
`nf-test`	Tests CI actions.
`<target>-apply`	Deploys to the provided target.
`<target>-tf`	Provides you a terraform shell for the provided target.
`<host>-ssh`	SSH into the provided host.
`nix build -f . network.nodes.<host>.deploy.system`	Build a system closure for the provided host.
