Nix, NixOS and Home Manager for mipmip's machine park

This is my mono-repository for my machines configuration and my dotfiles.

Features

• multi machine
• flakes
• Custom patched Suckless Terminal (st)

Mentional NUR's

• A 32 bits Brother printer driver
• Some Gnome Extensions packed directly from Github (useful is maintainers keep behind supporting the latest Gnome Versions)
• mip.rs, a fast and suckless markdown viewer written in Rust.
• WIP: Skull, a tool for managing git working copies on demand.
• some NUR crystal apps

Usage

clone:

cd ~
git clone --recurse-submodules git@github.com:mipmip/nixos.git
cd /etc
mv /etc/nixos /etc/nixos.bak
sudo ln -s /home/pim/nixos nixos

nixos-rebuild:

cd /etc/nixos
sudo nixos-rebuild switch --flake .#ojs

Home Manager:

cd /etc/nixos
home-manager switch  --flake .#pim@ojs --impure

Add Agenix file

1. add file registration in secrets/secrets.nix
2. cd secrets
3. create file or edit file agenix -e aws-credentials-copy.age
4. add file purpose to modules/nix-agenix.nix

example: agenix -i ~/.ssh/id_ed25519 -e aws-credentials-copy.age

MacOS Provisioning

For macOS provisioning I only use Home-Manager from Nix. Cli tools are declared in home-manager/programs/macos-bundle.nix. Other mac-apps are in home-manager/files-macos/Brewfile. Install them with brew bundle install

• install Homebrew
• install Nix on mac](https://nixos.org/download.html#nix-install-macos).
• then install Home Manager. See Home Manager Manual

NixOS Programming

Check for missing modules

when refactoring it's nice to quickly see which hosts have missing modules. To see this run:

./RUNME.sh missing_modules

Home-Manager Depreciated (remove once tested)

Make sure home-manager is installed. On Mac I home-manager as single user install. On nixos home-manager is installed automatically.

Create home dir conf:

mkdir -p ~/.config/nixpkgs
echo "{\n  allowUnfree = true;\n}" > ~/.config/nixpkgs/config.nix

Make the symlink ~/.config/nixpkgs/home.nix pointing to one of the home-confs located in ~/nixos/home-manager/

ln -s ~/nixos/home-manager/home-[some-home-conf].nix ~/.config/nixpkgs/

Test configuration with:

home-manager switch

Home-Manager

home-manager switch  --flake .#pim --impure

Features

Linux Desktop Highlights

I use GNOME as desktop environment with a few extensions to give me some features I'm used too from the time I used macOS as primary OS.

Programming and writing

I payed a lot of time optimizing my terminal and vim configuration. I use St with a few patches for better aesthetics.

My St/Vim writing configuration has a larger line height, a dedicated font, a pure white background together with a grayscale writing theme. Here's a pic showing my writing environment.

Private

Stage 2 of my security strategy is a git submodule with some configurations not relevant for public. This repo does not contain passwords or secrets.

Pine Phone Pesto

Build Image

Build from any nix machine with:

nix build './#pinephone-img'

If nix complains about some "experimental features", then add to the host's nix config: nix.extraOptions = "experimental-features = nix-command flakes";

flash with:

sudo dd if=$(readlink result) of=/dev/sdb bs=4M oflag=direct conv=sync status=progress

Then insert the SD card, battery into your pinephone and hold the power button for a few seconds until the power LED turns red. after releasing the power button, the LED should turn yellow, then green. you'll see the "mobile NixOS" splash screen and then be dropped into a TTY login prompt.

Update with copy-closure

build on host machine

nix build .\#nixosConfigurations.pinephone.config.system.build.toplevel --print-out-paths

copy to pinephone

nix-copy-closure --to root@192.168.13.103 ./result

on pinephone
