## Steps to deploy
1. Create a USB install medium from the official NixOS ISO and boot from it.
2. Review
[`../hosts/idols-ai/hardware-configuration.nix`](../hosts/idols-ai/hardware-configuration.nix)
against the target machine before installing; after the disk is mounted, regenerate it with
`nixos-generate-config --root /mnt` if the hardware differs.
### 1. Partition and mount with disko (recommended)

`@tmp`, `@swap`). Root is tmpfs; [preservation](https://github.com/nix-community/preservation) uses
`/persistent`.
