[Nix-dev] nixos/nixpkgs source used by iso installer?

[Marc Weber]

Does it make sense to use the nixos/nixpkgs version distributed with the
live cd:
- yes - installation might be faster

Does it make sense to always use latest:
- yes - for security reasons - and because user will update soon anyway?

Wich argument is stronger?

So should nixos-install found on the live cd be able to run
"nixos-checkout" (optionally)?
