# Installation Device {#sec-profile-installation-device}

Provides a basic configuration for installation devices like CDs.
This enables redistributable firmware, includes the
[Clone Config profile](#sec-profile-clone-config)
and a copy of the Nixpkgs channel, so `nixos-install`
works out of the box.

Documentation for [Nixpkgs](#opt-documentation.enable)
and [NixOS](#opt-documentation.nixos.enable) are
forcefully enabled (to override the
[Minimal profile](#sec-profile-minimal) preference); the
NixOS manual is shown automatically on TTY 8, udisks is disabled.
Autologin is enabled as `nixos` user, while passwordless
login as both `root` and `nixos` is possible.
Passwordless `sudo` is enabled too.
[NetworkManager](#opt-networking.networkmanager.enable) is
enabled and can be configured interactively with `nmtui`.

It is explained how to login, start the ssh server, and if available,
how to start the display manager.

Several settings are tweaked so that the installer has a better chance of
succeeding under low-memory environments.
