A new constructor function (like nsenter) is added in this patch. This function gets arguments from environment variables and its behaviour doesn't depend on a command line arguments. A program which calls factory.StartInitialization() must import the nsenter package. It looks ugly, but I don't know another way how to enter into CT from a go code.
