You should look at /mnt/etc/nixos/configuration.nix

/etc/nixos/configuration.nix defines the nixos configuration of the system in
the CD.

/mnt/etc/nixos/configuration.nix defines the system you want in your hard disk
(mounted at /mnt)

nixos-install uses some 'chroot /mnt ...' operations, so you may get messages
telling about /etc/nixos/configuration.nix, but you should understand that they
refer to /mnt. As you install a nixos (nixos-install), and not rebuild the CD
nixos (nixos-rebuild), I'm quite sure your trouble refers to
/mnt/etc/nixos/configuration.nix.
