Make an Raspberry Pi image to connect to a vnc server at startup with reconnect -- 2

We need a raspberry with the following function after starting up: (we connect the raspberry with a touchscreen to interact with a hosted application using VNC) - system starts without UI - system starts with network connection (cable) and fixed IP address (ip address configurable in a file) - system starts a VNC connection to another vnc server in full screen. (ip address of server configurable in a file) (The server hosts the touch-application) - when the network fails the VNC connection must reconnect automatically to the server - when the network fails the user can't interact with the raspberry. The raspberry must try to reconnect to the VNC server until the connection is back. - a VNC server is also running on the raspberry to remotely connect to the raspberry and configure the settings (ip addresses...) - full description of setup is needed in a document (installation and configuration) - reproduceable setup is needed - we need a stable solution (no home made rubbish) because it's for a production environment. - only experienced companies - we need full source and setup please specify in your proposal what linux OS you will use
