I.
something seems to have gone wrong, when I try now: e.g. nubox -public I get a python missing library:
ImportError: No module named nu_node
II. also, it asks me to rename the box again to peerbox, though it is named already
it asks me now thus also to reboot the box
better would be: to check if the hostname exists already
III. OK: the new nu.conf was created with rpcuser, rpcpassword and server entries
