OK, @jsrain just to be sure, do we want to keep it? ( It means we need to allow setup network in first stage and also in second and it can also cause problems when we want to partially configure network automatic and partially manually ). If it is such case, then we need to move network manual setup to second stage probably with different client than used in first stage. We will discuss it on friday meeting.

@thomas-fehr Thanks for valuable comments and pointers to possible problems
