My dotfiles - including my vim, terminal and font configs.
|
||||
Mostly focusing on setting things up on NixOS, but supporting other OSes where possible.
|
||||
My dotfiles - including my vim, terminal and font config.
|
||||
My current setup consists of multiple machines running NixOS.
|
||||
This is using flakes for reproducibility and home manager for setting up user-specific things.
|
||||
|
||||
## bootstrap new machine with NixOS:
|
||||
|
||||
1. boot the target machine from the livecd
|
||||
2. change password for the default user `nixos`
|
||||
3. ssh from another, already bootstrapped, machine

### flakes

|

```
|
||||
inputs = {
|
||||
nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable";
|
||||
};
|
||||
|
||||
outputs = { self, nixpkgs, ... }@inputs: {
|
||||
nixosConfigurations = {
|
||||
hyacinth = nixpkgs.lib.nixosSystem {
|
||||
system = "x86_64-linux";
|
||||
modules = [
|
||||
(import ./machines/hyacinth)
|
||||
];
|
||||
specialArgs = { inherit inputs; };
|
||||
};
|
||||
```
|
||||
Workstations are set up by running ` sudo nixos-rebuild switch --flake '.#'` and servers are by `nixos-rebuild switch --flake '.#servername' --target-host root@hostname`.
|
||||
I don't use home manager the program, everything is referenced from the top flake.
