# nixos

One flake, one machine: x86_64 UEFI desktop. Hyprland + greetd autologin,
Zen+Tridactyl, neovim, zsh+starship.

```
flake.nix                    all config (the `pc` system module + the `home` module)
hardware-configuration.nix   generic x86_64 UEFI profile — mounts by label, as-is
config/                      raw configs: hypr fuzzel nvim
```

Set `time.timeZone` in the `pc` module. Monitors, workspace placement and
keybinds live in `config/hypr/hyprland.conf`.

## Apply

The flake output is named after the hostname, so no `#target` is needed:

```sh
sudo nixos-rebuild switch --flake ~/nixos
nix flake update && sudo nixos-rebuild switch --flake ~/nixos   # update
```
Roll back = pick an older generation at boot.

## Install

No hardware generation needed — `hardware-configuration.nix` is generic and
mounts by the labels below. Boot the NixOS ISO, `sudo -i`:

```sh
parted /dev/nvme0n1 -- mklabel gpt \
  mkpart ESP fat32 1MiB 512MiB set 1 esp on \
  mkpart primary 512MiB 100%
mkfs.fat -F32 -n NIXBOOT /dev/nvme0n1p1
mkfs.ext4 -L NIXROOT    /dev/nvme0n1p2
mount /dev/disk/by-label/NIXROOT /mnt && mkdir -p /mnt/boot
mount /dev/disk/by-label/NIXBOOT /mnt/boot
git clone <private-remote> /mnt/root/nixos && cd /mnt/root/nixos
nixos-install --flake .#pc && reboot
```
Exotic storage controller won't boot? Add its module to
`availableKernelModules` in `hardware-configuration.nix`
(`nixos-generate-config --show-hardware-config` lists it).

## After first boot

`passwd` (ships `initialPassword = "changeme"`). If you land on a tty instead
of Hyprland, change greetd's `uwsm start hyprland` → `Hyprland`.
