##Step by step##
1. Boot the [installer](https://nixos.org/download.html#nixos-iso)
2. Get disk name
```$ lsblk```
3. Get disko config
```
$ curl https://git.kabtop.de/Kabbone/nixos-config/raw/branch/main/disko/btrfs_luks.nix -o /tmp/disko-config.nix
```
4. Adjust device name
5. Let disko partition the disk
```
$ sudo nix --experimental-features "nix-command flakes" run github:nix-community/disko -- --mode disko /tmp/disko-config.nix
```
6. Check if it got mounted
```$ mount | grep /mnt```
7. Continue with NixOS installation
Filesystem definitions come from disko, hence "--no-filesystems"
`Alternative:` continue with normal hardware-config
```
$ nixos-generate-config --no-filesystems --root /mnt
$ mv /tmp/disko-config.nix /mnt/etc/nixos
