The first action of Rudder Agent is to fetch the tools
directory from Rudder
Server. This directory is located at /opt/rudder/share/tools
on the Rudder
Server and at /var/rudder/tools
on the Node. If this directory is already
present, only changes will be updated.
The agent then try to fetch new Applied Policies from Rudder Server. Only requests from valid Nodes will be accepted. At first run and until the Node has been validated in Rudder, this step fails.
