Whether to accept Lix configuration from the nixConfig attribute of a flake. Doing so as a trusted user allows Nix flakes to gain root access on your machine if they set one of the several trusted-user-only settings that execute commands as root.

If set to true, such configuration will be accepted without asking; this is almost always a very bad idea. Setting this to ask will prompt the user each time whether to allow a certain configuration option set this way, and offer to optionally remember their choice. When set to false, the configuration will be automatically declined.

See multi-user installations for more details on the Lix security model.
