DWL

Installaion

Install NixOS

Follow the manual and install NixOS with any desktop environment and reboot.
Update the generated nixos configuration in /etc/nixos/configuration.nix.

The new configuration must have: user configuration, flakes enabled, cachix (optional), git, git-crypt, internet setup, firewall disabled

Check the configuration.nix example

Install host config

Reboot into NixOS, login with the user you created

Connect to internet

# The following commands will work if you enabled `networking.networkmanager.enable = true;`
$ nmtui
$ ping google.com

If ping google.com doesn't work, try updating your DNS

$ vim /etc/resolv.conf
# add `nameserver 8.8.8.8` to `/etc/resolv.conf`

Use local cachix, if you have 2 machines using the same nix config/channels (optional)
```
# Run on another machine, with nixos installed
$ nix-serve -p 8080

# On current/new machine, test
$ curl http://192.168.x.x:8080/nix-cache-info
```
On the current/new machine, update nix.settings.substituters config, add http://192.168.x.x:8080, then restart

Clone this repository into /home/<username>/.config/nix-config

$ git clone https://github.com/wochap/nix-config.git ~/.config/nix-config

Rebuild nixos with the host's specific config, for example, heres's a rebuild for my gdesktop

WARNING: First nixos-rebuild with device config can take several hours, maybe you want to disable some modules
```
# Go to nix-config folder
$ cd /home/<username>/.config/nix-config
$ nixos-rebuild boot --flake .#gdesktop
# or if you want to switch to a specialisation
# $ nixos-rebuild switch --flake .#gdesktop --specialisation hyprland-specialisation
```
Reboot so changes take effect

NOTE: If you encounter an error related to home-manager, it is likely due to a file collision, and you will need to remove a file. You can identify which files are in conflict with the following command: systemctl status home-manager-<username>.service. After resolving all the collisions, you can restart the home-manager-<username>.service.
Set password for new user <username> if you haven't
```
# for example
$ passwd gean
```
