## What it is
disko is a declarative disk partitioning and formatting tool for NixOS that lets you define disks, partitions, filesystems, and mount points as Nix configuration. It automates installation-time disk setup, supports disk image creation, and integrates with nixos-anywhere and disko-install.

## Use cases
- declaratively partition and format disks during NixOS installation
- set up unattended or automated NixOS installations
- rebuild identical disk layouts across multiple servers
- recover and re-provision disks after a system crash
- create bootable NixOS disk images from configuration
- remotely install NixOS with nixos-anywhere and disko
- configure LUKS encryption, LVM, ZFS, or btrfs layouts as code

## When to choose
- you use NixOS and want disk setup described in code alongside the rest of your configuration
- you need reproducible, unattended installations or identical server provisioning
- you want to generate disk images declaratively

## When to avoid
- you are not using NixOS or the Nix ecosystem
- you need a general-purpose interactive partitioning tool like fdisk or GParted
- you only need a one-off manual disk format
