What?

This is a repo that contains a set of Nix expressions used to build a custom Nix operating system that can be booted from a flash drive in the spirit of erasing my darlings.

Where?

Uhh, here.

When?

Check the commit history.

Why?

Why not?

But, seriously, I have a dream to be able to share development operating systems within projects and to be completely independent of any host OS installed to the hard disk of any machine that I own. This project allows me to recover from a hardware failure with "zero downtime" (TM).

How?

Easy. Get nix installed on some machine (or install NixOS which comes with nix package manager.

1. nix-build at the root of this repository.

or (if you want to customize user(s)) then run

1. nix-build --arg users "import ./custom-users.nix"

2. cat ./result/iso/johnos.iso > /dev/sdb (or use another tool to write the ISO to a flash drive)

where ./custom-users.nix is a file that you will write and looks something like

let
	pkgs = (import <nixpkgs> {});
in
{
	# change the key name below to change the user name from `acoolusername` to
	# whatever you want
	acoolusername = {
		password="super-secret-password";
		isNormalUser=true; # allow to log in
		extraGroups = ["wheel" "foo" "bar"];
		# find more packages at https://search.nixos.org/packages
		packages = with pkgs; [
			git	
			brave
			htop
			vscodium
			discord
		];
	};
}

Notes

1. The user defined first in this nix configuration will be automatically logged in

Further goals

• Support declarative secrets
• Encrypt / using LUKS
• Start using home-manager
