[Nix-dev] Problems building installation CD on Debian etch x86_64

Which does no longer work if you have small modifications ..
The alternative is setting up dstributed building so that your x64
machine can ask a i686 machine to do exactly those missing build jobs.

There are some system options and can read more about it here:
http://nixos.org/releases/nix/unstable/manual/#sec-distributed-builds

I've been using the distirubted build setup for quite a while now.

Sincerly
