Since nix-1.4, nix's corepkgs contain a fetchurl suitable for downloading the bootstrap binaries. Doing this will allow us to have a nixpkgs with no in-tree binaries without breaking the purity of the bootstrap (though for now, they are fetched in-tree until the binaries are added to nixos.org somewhere). As an additional small benefit, the in-tree binaries do not have to be hashed on every instantiation as they do now. The fetchurl in nix-1.2 and 1.3 isn't able to make binaries executable, so it can't be used for this case. In that case, attempting to build the bootstrap will show a message asking the user to manually download each file and add it to the store with nix-store --add (but the hash is ultimately the same, of course).

Sorry, this version of nix cannot download all of the bootstrap tools.

Please download ${args.url}, make it executable, add it to the store

with `nix-store --add', and try again.
