# A highly awesome system configuration

[![built with nix](https://builtwithnix.org/badge.svg)](https://builtwithnix.org)

### File structure

1. `config` - Main system configuration. `base-desktop.nix` contains lots of useful defaults.

2. `home-manager` - Holds most of the desktop configuration.

3. `modules` - A couple of custom options.

4. `overlays` - Contains riced and custom packages. Riced packages have the name prefix `g-`.

5. `hosts` - Contains host specific configuration.

6. `flake.nix` - Kickass flake config ;)

# ZFS Cheatsheet

## Create pool

```bash

zpool create -o ashift=12 -o autotrim=on -O compression=zstd -O acltype=posixacl -O xattr=sa -O atime=off -O mountpoint=legacy zroot sdx2

# with two mirrored drives

zpool create -o ashift=12 -o autotrim=on -O compression=zstd -O acltype=posixacl -O xattr=sa -O atime=off -O mountpoint=legacy zroot mirror sdx2 sdy2

```

- `autotrim` - Should be omitted for non-SSD storage.

- `ashift` - Requires research. this setting is device-specific, and many drives will lie.

## Setup partitions

```bash

mkfs.vfat -n BOOT -F32 /dev/sdx1

parted /dev/sdx set 1 boot on

mkdir /mnt/{home,boot,nix}

zfs create -o encryption=on -o keyformat=passphrase zroot/locker

zfs create zroot/locker/home

zfs create zroot/locker/nix

zfs create zroot/locker/os

mount -t zfs zroot/locker/os /mnt

mount -t zfs zroot/locker/home /mnt/home

mount -t zfs zroot/locker/nix /mnt/nix

mount /dev/sdx1 /mnt/boot

```

## NixOS config

```nix

{

  # needed for zfs. 4 random bytes (in hex)

  networking.hostId = "12345678";

  # or nicer implementation

  networking.hostId = builtins.substring 0 8 (builtins.hashString "md5" config.networking.hostName);

  # nixos documentation recommends setting these to false

  boot = {

      zfs.forceImportAll = false;

      zfs.forceImportRoot = false;

  };

}

```

## unmount and export all zfs stuff before leaving the live installer!!!

```bash

zpool export zroot

```
