[Nix-dev] nix on compute cluster?

2014-10-10 Thread Andreas Herrmann
Hi, How would you go about bringing the benefits of Nix to the users of a compute cluster? Assume the following cluster: A login node, a file-system node, and a number of compute nodes. All nodes run on a recent CentOS and are fairly homogeneous. The fs node holds all user data and some
