Workflow Concept

This is a diagram of the original concept for the client workflow.

Implementation

This is a slightly outdated but mostly accurate digram of how the various YaST components fit together.

There are unfortunately several limitations in YaST which made the implementation unnecessarily ugly. For example there is no easy way to communicate between a YaST process running as a limited user, and one running as root. So yast2-xml was used, to serialise/deserialise data structures for communication. yast2-xml is unable to handle arbitary formatted XML, so a perl module is used to perform the XML parsing itself.
