## Key Changes from Original Configuration
|
|
|
|
### ✅ Removed
|
|
- **nix-darwin** input and outputs
|
|
- **macOS/Darwin** conditionals (lines 54-58 in sh.nix)
|
|
- **WSL** hard-coded paths (lines 31-32 in tmux.nix)
|
|
- **Windows** checks (lines 115-117 in sh.nix)
|
|
|
|
### ✅ Added
|
|
- **System-level configuration** (configuration.nix)
|
|
- Boot loader setup (systemd-boot)
|
|
- Networking with NetworkManager
|
|
- User account definition
|
|
- System timezone and locale
|
|
- Nix flakes enabled
|
|
|
|
- **Hardware configuration template** (hardware-configuration.nix)
|
|
- Placeholder for NixOS-generated config
|
|
- Must be replaced during installation
|
|
|
|
### ✅ Modified
|
|
- **Home Manager integration**
|
|
- Now runs as NixOS module (not standalone)
|
|
- useGlobalPkgs enabled
|
|
- Removed allowUnfree (handled at system level)
|
|
|
|
- **Shell configuration** (modules/sh.nix)
|
|
- Removed all platform-specific conditionals
|
|
- Clean Linux-only configuration
|
|
- Added `profileExtra` for .profile sourcing
|
|
|
|
- **Tmux configuration** (modules/tmux.nix)
|
|
- Commented out note keybindings (C-n, C-p)
|
|
- Paths need to be updated for NixOS environment
|
|
|
|
- **Development tools** (modules/dev.nix)
|
|
- Custom packages commented out:
|
|
- claude-code
|
|
- opencode
|
|
- gemini-cli
|
|
- TODO notes added for integration
|
|
|
|
## Validation Status
|
|
|
|
✅ Flake syntax is valid
|
|
✅ Configuration evaluates successfully
|
|
✅ All module imports resolve correctly
|
|
✅ No blocking errors found
|
|
|
|
⚠️ Requires `--impure` flag due to NIX_LD settings
|
|
|
|
## What Needs to Be Done Before Use
|
|
|
|
### 🔴 Critical (Must Do)
|
|
1. **Replace hardware-configuration.nix**
|
|
```bash
|
|
sudo nixos-generate-config --show-hardware-config > nixos/hardware-configuration.nix
|
|
```
|
|
|
|
2. **Update hostname** in configuration.nix
|
|
- Currently set to: "nixos"
|
|
- Change to your actual hostname
|
|
|
|
3. **Verify boot loader** choice in configuration.nix
|
|
- UEFI: systemd-boot (currently enabled)
|
|
- BIOS: GRUB (commented out)
|
|
|
|
### 🟡 Important (Should Do)
|
|
1. **Verify timezone** in configuration.nix
|
|
- Currently: "Europe/Berlin"
|
|
|
|
2. **Check locale settings** in configuration.nix
|
|
- Currently: en_US.UTF-8 / de_DE.UTF-8
|
|
|
|
3. **Verify nvim lua files** exist at:
|
|
- `/home/pan/dev/config/dot/nvim/base.lua`
|
|
- `/home/pan/dev/config/dot/nvim/keymaps.lua`
|
|
- `/home/pan/dev/config/dot/nvim/plugins.lua`
|
|
- `/home/pan/dev/config/dot/nvim/filetype.lua`
|
|
|
|
### 🟢 Optional (Nice to Have)
|
|
1. **Update tmux note paths** in modules/tmux.nix (C-n, C-p keybindings)
|
|
2. **Add custom packages** (claude-code, opencode, gemini-cli)
|
|
3. **Review and customize** any other settings
|
|
|
|
## How to Apply
|
|
|
|
### Test Build (Recommended First)
|
|
```bash
|
|
cd /home/pan/dev/config/dot/nix/nixos
|
|
sudo nixos-rebuild build --flake .#nixos --impure
|
|
```
|
|
|
|
### Apply Configuration
|
|
```bash
|
|
cd /home/pan/dev/config/dot/nix/nixos
|
|
sudo nixos-rebuild switch --flake .#nixos --impure
|
|
```
|
|
|
|
### Update Packages
|
|
```bash
|
|
nix flake update
|
|
sudo nixos-rebuild switch --flake .#nixos --impure
|
|
```
|
|
|
|
## Verification Checklist
|
|
|
|
After applying the configuration, verify:
|
|
|
|
- [ ] System boots successfully
|
|
- [ ] User 'pan' can login
|
|
- [ ] Zsh loads with Prezto theme
|
|
- [ ] fzf keybindings work (Ctrl+R)
|
|
- [ ] zoxide works (`cd` command)
|
|
- [ ] Tmux starts without errors
|
|
- [ ] Neovim opens with all plugins
|
|
- [ ] Git config shows correct user
|
|
- [ ] Lazygit and Jujutsu work
|
|
- [ ] Taskwarrior shows version 3.x
|
|
- [ ] Direnv loads .envrc files
|
|
|
|
## Files Preserved
|
|
|
|
The original Home Manager configuration remains untouched:
|
|
- `/home/pan/dev/config/dot/nix/flake.nix`
|
|
- `/home/pan/dev/config/dot/nix/common.nix`
|
|
- `/home/pan/dev/config/dot/nix/user/*`
|
|
|
|
You can continue using the Ubuntu setup alongside this NixOS configuration.
