TODO: improve Instance Parameters =================== Zope Parameters --------------- Needed by software-type development (default) and zope. frontend-software-url ~~~~~~~~~~~~~~~~~~~~~ Software URL of an existing frontend. XXX: meaning should change (or it will go away) in order to be resilient to software updates - as they are visible at software-url level. If it is not provided, no frontend will be requested. frontend-instance-guid ~~~~~~~~~~~~~~~~~~~~~~ GUID of frontend instance. Not perfect yet: if that instance is replaced, slaves have to be reconfigured. Mandatory only if frontend-software-url is also provided. XXX: should be complemented (or replaced) by more flexible and precise criteria. frontend-software-type (optional) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Frontend software type as defined by the software relase at frontend-software-url. frontend-domain (optional) ~~~~~~~~~~~~~~~~~~~~~~~~~~ Domain name frontend must recognise as belonging to this instance.
