Installation Device

Provides a basic configuration for installation devices like CDs. This enables redistributable firmware, includes the Clone Config profile and a copy of the Nixpkgs channel, so nixos-install works out of the box.

Documentation for Nixpkgs and NixOS are forcefully enabled (to override the Minimal profile 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. wpa_supplicant is enabled, but configured to not autostart.

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.
