Argh, you're right, nix.proxy determines the environment variables for
nix-daemon, there's no proxy setting in the nix configuration file :-(

So while this will set build options that are defined in the nixos config,
it doesn't help with proxying.

So it's back to not doing the build with nix-daemon, but as root with the
proper proxy variables set. Just sudo -s, set the variables and do a
nixos-rebuild.

Another option would be to set up iptables to send all http traffic through
a transparent proxy but that's probably silly :-D.

Wout.
