# checks first if the client was already configured and if it has an valid serial
# if not it runs the autoconfiguration script
# these settings will be used for client setup
#
# if client was valid it first will check if his settings against the server
# if no changes are at server side they will be kept, if yes the get updated. 
# the server settings has higher priority.
