The use of Nix 2.0 significantly simplifies the installer, since we can just pass a different store URI (--store /mnt) - it's no longer needed to set up a chroot environment for the build, and to bootstrap Nix into the chroot. Also, commands that need to run in the installation (namely boot loader installation and setting a root password) are now executed using nixos-enter. This also removes the need for nixos-prepare-root since any required initialisation is done by Nix or by the activation script.
