  + ⚠ The demos build a number obscure variants of packages that are not provided by https://cache.nixos.org/, so this might take a long time the first time you run them.

  + Once the packages are present in the Nix store the scripts run in seconds (in automatic mode).

  [4.179]
  + ⚠ The container-related demos use [rootless Podman](https://github.com/containers/podman/blob/main/docs/tutorials/rootless_tutorial.md), which needs some configuration files.

  + If they don't exist yet they will be created in `~/.config/containers/` and will not removed. The scripts do make a best-effort attempt at removing any containers that are created.

  + Rootless Podman has some special requirements; most of them are provided by Nix, but e.g. [`/etc/subuid` and `/etc/subgid` configuration](https://github.com/containers/podman/blob/main/docs/tutorials/rootless_tutorial.md#etcsubuid-and-etcsubgid-configuration) must be fixed by an administrator.
