|
## Overview
|
|
|
|
User accounts are defined in `users.nix` but are **not enabled by default**. Each host must explicitly enable users in `inventory.nix`.
|
|
|
|
**Always-enabled users:**
|
|
- `root` - System administrator (enable: true)
|
|
- `engr-ugaif` - Innovation Factory default account (enable: true)
|
|
|
|
All other users are disabled by default and must be explicitly enabled per-host.
|
|
|
|
## Quick Start
|
|
|
|
### 1. Define User in users.nix
|
|
|
|
```nix
|
|
athenix.users.myuser = {
|
|
description = "John Doe";
|
|
extraGroups = [ "wheel" "networkmanager" ];
|
|
shell = pkgs.zsh;
|
|
hashedPassword = "$6$..."; # Generate with: mkpasswd -m sha-512
|
|
opensshKeys = [ "ssh-ed25519 AAAA..." ];
|
|
};
|
|
```
|
|
|
|
### 2. Enable on Hosts in inventory.nix
|
|
|
|
```nix
|
|
nix-laptop = {
|
|
devices = 5;
|
|
overrides.athenix.users.myuser.enable = true;
|
|
};
|
|
```
|
|
|
|
### 3. Users can now log in
|
|
|
|
Users defined and enabled this way are automatically created on the system.
|
|
|
|
## Defining Users
|
|
|
|
Define users in `users.nix` under `athenix.users`:
|
|
|
|
### Inline User Definition
|
|
|
|
```nix
|
|
athenix.users.myuser = {
|
|
description = "My Full Name";
|
|
extraGroups = [ "wheel" "networkmanager" ];
|
|
shell = pkgs.zsh;
|
|
hashedPassword = "$6$...";
|
|
opensshKeys = [ "ssh-ed25519 AAAA..." ];
|
|
useZshTheme = true;
|
|
useNvimPlugins = true;
|
|
};
|
|
```
|
|
|
|
### External User Configuration
|
|
|
|
Reference an external Git repository (recommended for personal dotfiles):
|
|
|
|
```nix
|
|
athenix.users.myuser.external = builtins.fetchGit {
|
|
url = "https://git.factory.uga.edu/username/dotfiles";
|
|
rev = "abc123..."; # Pin to specific commit
|
|
};
|
|
```
|
|
|
|
The external repository should contain:
|
|
- `user.nix` (required) - User account options AND home-manager configuration
|
|
- `nixos.nix` (optional) - System-level configuration
|
|
|
|
See [External User Configurations](#external-user-configurations) section below.
|
|
|
|
## User Account Options
|
|
|
|
### `description`
|
|
|
|
Full name or description of the user.
|
|
|
|
**Type:** String
|
|
|
|
```nix
|
|
athenix.users.myuser.description = "John Doe";
|
|
```
|
|
|
|
### `extraGroups`
|
|
|
|
Additional Unix groups for the user. Default is empty.
|
|
|
|
**Type:** List of strings
|
|
|
|
**Common groups:**
|
|
- `"wheel"` - Sudo access
|
|
- `"networkmanager"` - Network configuration
|
|
- `"docker"` - Docker and Podman access
|
|
- `"video"` - Video device access (GPU, displays)
|
|
- `"audio"` - Audio device access
|
|
- `"input"` - Input devices (keyboards, mice)
|
|
- `"kvm"` - KVM virtual machine access
|
|
- `"libvirtd"` - Libvirt daemon access
|
|
|
|
```nix
|
|
athenix.users.myuser.extraGroups = [
|
|
"wheel"
|
|
"networkmanager"
|
|
"docker"
|
|
"video"
|
|
];
|
|
```
|
|
|
|
### `shell`
|
|
|
|
Login shell for the user.
|
|
|
|
**Type:** Package
|
|
|
|
**Default:** `pkgs.bash`
|
|
|
|
```nix
|
|
athenix.users.myuser.shell = pkgs.zsh;
|
|
# or
|
|
athenix.users.myuser.shell = pkgs.fish;
|
|
```
|
|
|
|
### `hashedPassword`
|
|
|
|
Password hash for the user. Use `!` to disable password login (SSH keys only).
|
|
|
|
**Type:** String (SHA-512 hash)
|
|
|
|
**Generation:**
|
|
```bash
|
|
# Generate a hashed password
|
|
mkpasswd -m sha-512
|
|
|
|
# Or interactively
|
|
mkpasswd -m sha-512 -c
|
|
```
|
|
|
|
```nix
|
|
athenix.users.myuser.hashedPassword = "$6$...";
|
|
|
|
# Disable password login (require SSH keys)
|
|
athenix.users.myuser.hashedPassword = "!";
|
|
```
|
|
|
|
### `opensshKeys`
|
|
|
|
SSH public keys for remote access. Users without SSH keys require password login.
|
|
|
|
**Type:** List of strings
|
|
|
|
```nix
|
|
athenix.users.myuser.opensshKeys = [
|
|
"ssh-ed25519 AAAA... user@laptop"
|
|
"ssh-rsa AAAA... user@desktop"
|
|
];
|
|
```
|
|
|
|
**Getting your SSH public key:**
|
|
```bash
|
|
# Print your public key
|
|
cat ~/.ssh/id_ed25519.pub
|
|
|
|
# Generate a new key if needed
|
|
ssh-keygen -t ed25519 -C "user@host"
|
|
```
|
|
|
|
### `useZshTheme`
|
|
|
|
Apply system Zsh theme configuration to this user (if using Zsh as shell).
|
|
|
|
**Type:** Boolean
|
|
|
|
**Default:** `true`
|
|
|
|
```nix
|
|
athenix.users.myuser.useZshTheme = true;
|
|
```
|
|
|
|
### `useNvimPlugins`
|
|
|
|
Apply system Neovim configuration and plugins to this user.
|
|
|
|
**Type:** Boolean
|
|
|
|
**Default:** `true`
|
|
|
|
```nix
|
|
athenix.users.myuser.useNvimPlugins = true;
|
|
```
|
|
|
|
## Enabling Users on Hosts
|
|
|
|
Users are **not enabled by default**. Enable them in `inventory.nix`:
|
|
|
|
### Enable on All Devices in a Group
|
|
|
|
```nix
|
|
nix-laptop = {
|
|
devices = 5;
|
|
overrides.athenix.users.myuser.enable = true;
|
|
};
|
|
```
|
|
|
|
### Enable on Specific Devices
|
|
|
|
```nix
|
|
nix-desktop = {
|
|
devices = {
|
|
"1".athenix.users.admin.enable = true;
|
|
"2".athenix.users.staff.enable = true;
|
|
"3".athenix.users.staff.enable = true;
|
|
};
|
|
};
|
|
```
|
|
|
|
### Enable Multiple Users
|
|
|
|
```nix
|
|
nix-laptop = {
|
|
devices = 5;
|
|
overrides = {
|
|
athenix.users.student.enable = true;
|
|
athenix.users.teacher.enable = true;
|
|
};
|
|
};
|
|
```
|
|
|
|
### Using `athenix.forUser` Convenience
|
|
|
|
Quick setup for single-user systems (especially WSL):
|
|
|
|
```nix
|
|
nix-wsl = {
|
|
devices = {
|
|
"alice".athenix.forUser = "alice-uga";
|
|
"bob".athenix.forUser = "bob-uga";
|
|
};
|
|
};
|
|
```
|
|
|
|
This automatically enables the user and sets it as the default WSL user.
|
|
|
|
## External User Configurations
|
|
|
|
External user configurations (dotfiles) allow users to maintain their own home-manager setup in separate repositories.
|
|
|
|
### Repository Structure
|
|
|
|
```
|
|
my-dotfiles/
|
|
├── user.nix # Required: User options + home-manager config
|
|
├── nixos.nix # Optional: System-level configuration
|
|
└── config/ # Optional: Your actual dotfiles
|
|
├── bashrc
|
|
├── zshrc
|
|
├── vimrc
|
|
└── ...
|
|
```
|
|
|
|
### user.nix (Required)
|
|
|
|
This file must provide BOTH user account options AND home-manager configuration:
|
|
|
|
```nix
|
|
{ inputs, ... }:
|
|
{ config, lib, pkgs, osConfig ? null, ... }:
|
|
{
|
|
# ========== User Account Configuration ==========
|
|
# These options define the user account itself
|
|
athenix.users.myusername = {
|
|
description = "My Full Name";
|
|
extraGroups = [ "wheel" "docker" "networkmanager" ];
|
|
shell = pkgs.zsh;
|
|
hashedPassword = "!"; # SSH keys only
|
|
opensshKeys = [
|
|
"ssh-ed25519 AAAA... user@host"
|
|
];
|
|
useZshTheme = true;
|
|
useNvimPlugins = true;
|
|
};
|
|
|
|
# ========== Home Manager Configuration ==========
|
|
# User environment, packages, and dotfiles
|
|
|
|
home.packages = with pkgs; [
|
|
vim
|
|
ripgrep
|
|
fzf
|
|
] ++ lib.optional (osConfig.athenix.sw.type or null == "desktop") firefox;
|
|
|
|
programs.git = {
|
|
enable = true;
|
|
userName = "My Name";
|
|
userEmail = "me@example.com";
|
|
extraConfig = {
|
|
init.defaultBranch = "main";
|
|
core.editor = "vim";
|
|
};
|
|
};
|
|
|
|
programs.zsh = {
|
|
enable = true;
|
|
initExtra = ''
|
|
# Your Zsh configuration
|
|
'';
|
|
};
|
|
|
|
# Manage dotfiles
|
|
home.file.".config/zshrc".source = ./config/zshrc;
|
|
home.file.".config/bashrc".source = ./config/bashrc;
|
|
home.file.".vimrc".source = ./config/vimrc;
|
|
}
|
|
```
|
|
|
|
### nixos.nix (Optional)
|
|
|
|
System-level configuration for this user (rarely needed):
|
|
|
|
```nix
|
|
{ inputs, ... }:
|
|
{ config, lib, pkgs, ... }:
|
|
{
|
|
# System-level configuration for this user
|
|
users.users.myusername.extraGroups = [ "docker" ];
|
|
environment.systemPackages = [ pkgs.docker ];
|
|
}
|
|
```
|
|
|
|
### Using External User Configuration
|
|
|
|
In `users.nix`:
|
|
|
|
```nix
|
|
athenix.users.myuser.external = builtins.fetchGit {
|
|
url = "https://git.factory.uga.edu/username/dotfiles";
|
|
rev = "abc123..."; # Pin to specific commit
|
|
};
|
|
```
|
|
|
|
Then enable on hosts in `inventory.nix`:
|
|
|
|
```nix
|
|
nix-laptop = {
|
|
devices = 5;
|
|
overrides.athenix.users.myuser.enable = true;
|
|
};
|
|
```
|
|
|
|
### External Module Parameters
|
|
|
|
The `user.nix` module receives:
|
|
|
|
- **`inputs`** - All flake inputs (nixpkgs, home-manager, etc.)
|
|
- **`config`** - Home-manager configuration
|
|
- **`lib`** - Nixpkgs library functions
|
|
- **`pkgs`** - Package set
|
|
- **`osConfig`** - OS-level configuration (read-only, can be used for conditional setup)
|
|
|
|
### Creating External User Configuration
|
|
|
|
Use the template:
|
|
|
|
```bash
|
|
nix flake init -t git+https://git.factory.uga.edu/UGA-Innovation-Factory/athenix.git#user
|
|
```
|
|
|
|
## Password Management
|
|
|
|
### Generate Password Hash
|
|
|
|
```bash
|
|
# Interactive (won't echo)
|
|
mkpasswd -m sha-512 -c
|
|
|
|
# From string
|
|
echo "mypassword" | mkpasswd -m sha-512 -s
|
|
```
|
|
|
|
### Disable Password Login
|
|
|
|
Set `hashedPassword = "!"` and provide SSH keys:
|
|
|
|
```nix
|
|
athenix.users.myuser = {
|
|
description = "SSH-only user";
|
|
hashedPassword = "!";
|
|
opensshKeys = [ "ssh-ed25519 AAAA..." ];
|
|
};
|
|
```
|
|
|
|
### Update User Password on Running System
|
|
|
|
```bash
|
|
# As the user
|
|
passwd
|
|
|
|
# As root (to change another user's password)
|
|
sudo passwd username
|
|
```
|
|
|
|
## SSH Keys
|
|
|
|
### Add SSH Keys to a User
|
|
|
|
```nix
|
|
athenix.users.myuser.opensshKeys = [
|
|
"ssh-ed25519 AAAA... user@laptop"
|
|
"ssh-ed25519 BBBB... user@desktop"
|
|
];
|
|
```
|
|
|
|
### Get Your SSH Public Key
|
|
|
|
```bash
|
|
# Display your public key
|
|
cat ~/.ssh/id_ed25519.pub
|
|
|
|
# Or for RSA
|
|
cat ~/.ssh/id_rsa.pub
|
|
```
|
|
|
|
### Generate New SSH Key
|
|
|
|
```bash
|
|
# Ed25519 (recommended)
|
|
ssh-keygen -t ed25519 -C "user@host"
|
|
|
|
# RSA (older systems)
|
|
ssh-keygen -t rsa -b 4096 -C "user@host"
|
|
```
|
|
|
|

## External User Configurations
|
|
|
|
Users can maintain their dotfiles and home-manager configuration in separate Git repositories.
|
|
|
|
### Basic External Configuration
|
|
|
|
In `users.nix`:
|
|
|
|
```nix
|
|
myuser = {
|
|
# Basic options can be set here OR in the external module's user.nix
|
|
description = "My Name";
|
|
extraGroups = [ "wheel" ];
|
|
hashedPassword = "$6$...";
|
|
|
|
# Point to external configuration repository
|
|
external = builtins.fetchGit {
|
|
url = "https://git.factory.uga.edu/username/dotfiles";
|
|
rev = "abc123..."; # Pin to specific commit
|
|
};
|
|
};
|
|
```
|
|
|
|
### External Repository Structure

### What External Modules Receive
|
|
|
|
**In user.nix:**
|
|
- `inputs` - Flake inputs (nixpkgs, home-manager, etc.)
|
|
- `config` - Configuration (NixOS or home-manager depending on import context)
|
|
- `lib` - Nixpkgs library functions
|
|
- `pkgs` - Package set
|
|
- `osConfig` - (home-manager context only) OS-level configuration
|
|
|
|
### How External Modules Are Loaded
|
|
|
|
The `user.nix` module serves a dual purpose and is imported in **two contexts**:
|
|
|
|
1. **NixOS Module Context (User Options)**: The module is imported as a NixOS module where `athenix.users.<username>` options are read to define the user account (description, shell, groups, SSH keys, etc.). These options override any defaults set in `users.nix`.
|
|
|
|
2. **Home-Manager Context**: The same module is imported into home-manager where `home.*`, `programs.*`, and `services.*` options configure the user's environment, packages, and dotfiles.
|
|
|
|
**Key insight:** A single `user.nix` file contains both account configuration AND home environment configuration. The system automatically imports it in the appropriate contexts.
|
|
|
|
**Example:** The user account options (like `shell`, `extraGroups`) are read during NixOS evaluation, while home-manager options (like `home.packages`, `programs.git`) are used when building the user's home environment.
|
|
|
|
**In nixos.nix:**
|
|
- `inputs` - Flake inputs
|
|
- `config` - NixOS configuration
|
|
- `lib` - Nixpkgs library functions
|
|
- `pkgs` - Package set
|
|
|
|
### Alternative Configuration Methods
|
|
|
|
**Local path (for testing):**
|
|
```nix
|
|
external = /home/username/dev/dotfiles;
|
|
```
|
|
|
|
**Note:** User options can be set in users.nix OR in the external module's user.nix file. For custom packages and environment configuration without external modules, create a local module and reference it with `extraImports`.
|
|
|
|
### Create User Template
|
|
|
|
```bash
|
|
nix flake init -t git+https://git.factory.uga.edu/UGA-Innovation-Factory/athenix.git#user
|
|
```
|
|
|
|
See [templates/user/README.md](../templates/user/README.md) for complete template.
|
|
|
|
## Enabling Users on Hosts
|
|
|
|
Users must be explicitly enabled on each host in `inventory.nix`.
|
|
|
|
### Method 1: Enable in Overrides (All Devices)
|
|
|
|
```nix
|
|
nix-laptop = {
|
|
devices = 5;
|
|
overrides = {
|
|
athenix.users.student.enable = true; # All 5 laptops get this user
|
|
};
|
|
};
|
|
```
|
|
|
|
### Method 2: Enable per Device
|
|
|
|
```nix
|
|
nix-desktop = {
|
|
devices = {
|
|
"1".athenix.users.alice.enable = true;
|
|
"2".athenix.users.bob.enable = true;
|
|
"3" = {
|
|
athenix.users.alice.enable = true;
|
|
athenix.users.bob.enable = true;
|
|
};
|
|
};
|
|
};
|
|
```
|
|
|
|
### Method 3: Convenience Option (athenix.forUser)
|
|
|
|
Quick setup for single-user systems:
|
|
|
|
```nix
|
|
nix-wsl = {
|
|
devices = {
|
|
"alice".athenix.forUser = "alice-user"; # Automatically enables alice-user
|
|
"bob".athenix.forUser = "bob-user";
|
|
};
|
|
};
|
|
```
|
|
|
|
This is equivalent to `athenix.users.alice-user.enable = true`.
|
|
|
|
## Password Management
|
|
|
|
### Generate Hashed Password
|
|
|
|
```bash
|
|
mkpasswd -m sha-512
|
|
# Enter password when prompted
|
|
# Copy the output hash
|
|
```
|
|
|
|
### In users.nix
|
|
|
|
```nix
|
|
myuser = {
|
|
hashedPassword = "$6$rounds=656000$..."; # Paste hash here
|
|
};
|
|
```
|
|
|
|
### Disable Password Login
|
|
|
|
```nix
|
|
myuser = {
|
|
hashedPassword = "!"; # Locks password, SSH key only
|
|
opensshKeys = [ "ssh-ed25519 ..." ];
|
|
};
|
|
```
|
|
|
|
### Change Password Later
|
|
|
|
On the system:
|
|
```bash
|
|
sudo passwd myuser
|
|
```
|
|
|
|
Or regenerate hash and update `users.nix`.
|
|
|
|
## SSH Keys
|
|
|
|
### Adding SSH Keys
|
|
|
|
```nix
|
|
myuser = {
|
|
opensshKeys = [
|
|
"ssh-ed25519 AAAAC3Nza... user@laptop"
|
|
"ssh-rsa AAAAB3NzaC1... user@desktop"
|
|
];
|
|
};
|
|
```
|
|
|
|
### Generate SSH Key
|
|
|
|
```bash
|
|
ssh-keygen -t ed25519 -C "user@hostname"
|
|
cat ~/.ssh/id_ed25519.pub # Copy this
|
|
```
|
|
|
|
### Multiple Keys
|
|
|
|
Users can have multiple SSH keys for different machines:
|
|
|
|
```nix
|
|
opensshKeys = [
|
|
"ssh-ed25519 ... user@work-laptop"
|
|
"ssh-ed25519 ... user@home-desktop"
|
|
"ssh-ed25519 ... user@tablet"
|
|
];
|
|
```
|
|
|
|
## Examples
|
|
|
|
### Basic User
|
|
|
|
```nix
|
|
student = {
|
|
description = "Student Account";
|
|
extraGroups = [ "networkmanager" ];
|
|
shell = pkgs.bash;
|
|
hashedPassword = "$6$...";
|
|
};
|
|
```
|
|
|
|
### Admin User with SSH
|
|
|
|
```nix
|
|
admin = {
|
|
description = "System Administrator";
|
|
extraGroups = [ "wheel" "networkmanager" "docker" ];
|
|
shell = pkgs.zsh;
|
|
hashedPassword = "$6$...";
|
|
opensshKeys = [
|
|
"ssh-ed25519 AAAA... admin@laptop"
|
|
];
|
|
};
|
|
```
|
|
|
|
### User with External Configuration
|
|
|
|
```nix
|
|
developer = {
|
|
description = "Developer";
|
|
extraGroups = [ "wheel" "docker" ];
|
|
shell = pkgs.zsh;
|
|
hashedPassword = "$6$...";
|
|
external = builtins.fetchGit {
|
|
url = "https://git.factory.uga.edu/username/dotfiles";
|
|
rev = "abc123def456...";
|
|
};
|
|
};
|
|
```
|
|
|
|
### WSL User
|
|
|
|
```nix
|
|
wsl-user = {
|
|
description = "WSL User";
|
|
extraGroups = [ "wheel" ];
|
|
shell = pkgs.zsh;
|
|
hashedPassword = "$6$...";
|
|
external = builtins.fetchGit {
|
|
url = "https://git.factory.uga.edu/username/dotfiles";
|
|
rev = "abc123...";
|
|
};
|
|
};
|
|
```
|
|
|
|
Enable in inventory.nix:
|
|
```nix
|
|
nix-wsl = {
|
|
devices."my-wsl".athenix.forUser = "wsl-user";
|
|
};
|
|
```
|
|
|
|
### User Without System Themes
|
|
|
|
For users who want complete control over their shell/editor:
|
|
|
|
```nix
|
|
poweruser = {
|
|
description = "Power User";
|
|
extraGroups = [ "wheel" ];
|
|
shell = pkgs.zsh;
|
|
hashedPassword = "$6$...";
|
|
useZshTheme = false; # Don't apply system theme
|
|
useNvimPlugins = false; # Don't apply system nvim config
|
|
external = builtins.fetchGit {
|
|
url = "https://github.com/username/custom-dotfiles";
|
|
rev = "abc123...";
|
|
};
|
|
};
|
|
```
|
|
|
|
## Theme Integration
|
|
|
|
### System Zsh Theme
|
|
|
|
When `useZshTheme = true` (default), the system applies:
|
|
- Oh My Posh with custom theme
|
|
- History substring search
|
|
- Vi mode (for non-root users)
|
|
- Zsh plugins (zplug)
|
|
|
|
Disable if you want full control in your dotfiles.
|
|
|
|
### System Neovim Config
|
|
|
|
When `useNvimPlugins = true` (default), the system applies:
|
|
- LazyVim distribution
|
|
- TreeSitter parsers
|
|
- Language servers
|
|
|
|
Disable if you want to configure Neovim yourself.
|
|
|
|
## Troubleshooting
|
|
|
|
### User Can't Login
|
|
|
|
**Check if enabled on host:**
|
|
```bash
|
|
nix eval .#nixosConfigurations.nix-laptop1.config.athenix.users.myuser.enable
|
|
```
|
|
|
|
**Check if user exists:**
|
|
```bash
|
|
# On the system
|
|
id myuser
|
|
```
|
|
|
|
### SSH Key Not Working
|
|
|
|
**Check key in configuration:**
|
|
```bash
|
|
nix eval .#nixosConfigurations.nix-laptop1.config.users.users.myuser.openssh.authorizedKeys.keys
|
|
```
|
|
|
|
**Verify key format:**
|
|
- Should start with `ssh-ed25519`, `ssh-rsa`, or `ssh-dss`
|
|
- Should be all on one line
|
|
- Should end with comment (optional)
|
|
|
|
### External Config Not Loading
|
|
|
|
**Check repository access:**
|
|
```bash
|
|
git ls-remote https://git.factory.uga.edu/username/dotfiles
|
|
```
|
|
|
|
**Verify structure:**
|
|
- Must have `user.nix` at repository root
|
|
- `nixos.nix` is optional
|
|
- Check file permissions
|
|
|
|
**Test with local path first:**
|
|
```nix
|
|
external = /path/to/local/dotfiles;
|
|
```
