Introduction
nix-config - My Nix Configuration
This is not actively used for all my machines. I've moved back to Chezmoi as a dotfile manager.
See the full documentation at szinn.github.io/nix-config.
I manage my personal machines using Nix and Home-Manager.
The machines consist of:
| Machine | System | Purpose |
|---|---|---|
| hera | x86_64-linux | Intel NUC for running NixOS bare metal |
| titan | x86_64-linux | Intel NUC for running NixOS bare metal |
| macvm (not active) | aarch64-darwin | Nix-Darwin VM running in Parallels on MacBook |
| nixvm (not active) | aarch64-linux | NixOS VM running in Parallels on MacBook |
| odin (not active) | aarch64-darwin | Main MacBook Pro laptop |
| ragnar (not active) | x86_64-linux | NAS server |
Bootstrapping MacOS Machines
Darwin machines can be bootstrapped from the nix-config repository directly.
bash -c "$(curl -LsS https://raw.githubusercontent.com/szinn/nix-config/main/bootstrap.sh)"
At this point, NIX should be installed. Restart the shell.
To bootstrap the configuration now, run
nix run --extra-experimental-features nix-command --extra-experimental-features flakes nix-darwin -- switch --flake .#$(hostname -s)
There might be a few files in /etc that need renaming to complete the installation.
sudo mv /etc/nix/nix.conf /etc/nix.conf.before-nix-darwin
sudo mv /etc/shells /etc/shells.before-nix-darwin
sudo mv /etc/zshenv /etc/zshenv.before-nix-darwin
Afterwards, if the configuration is touched, darwin-rebuild is required to run the updates.
git add . ; darwin-rebuild switch --flake .#$(hostname -s)
I have MacOS aliases dupb (darwin update build) to do a build only and show what changes. dup (darwin update) does the build and an install.
Bootstrapping NixOS Machines
The process for bootstrapping a NixOS machine is essentially following the VM process
