[Nix-dev] Haskell NG: Still no binaries

IMHO, "nix-env" should pass those options on to the daemon, i.e. it
should not be necessary to hard-code hydra.cryp.to as a global binary
cache for this to work.

For example, when I run

  $ echo $NIX_REMOTE
  daemon
  $ nix-build --option extra-binary-caches http://hydra.example.org "<nixpkgs>" -A libreoffice --dry-run
  download-from-binary-cache.pl: binary cache ‘http://hydra.example.org’ is not trusted (please add it to ‘trusted-binary-caches’ in /etc/nix/nix.conf)
  these derivations will be built:
  [...]

..., then I get an error message about the untrusted cache that would
make no sense if the daemon wouldn't respect the setting from the
command line.

Just out of curiosity, did you configure

  nix.trustedBinaryCaches = [ http://hydra.nixos.org http://hydra.cryp.to ];

in your configuration.nix?

Best regards,
