def lib::config::ConfigWriter::Update (   self,
  target 
)

Notify function to be called after updates.

This function must be called when an object (as returned by
GetInstanceInfo, GetNodeInfo, GetCluster) has been updated and the
caller wants the modifications saved to the backing store. Note
that all modified objects will be saved, but the target argument
is the one the caller wants to ensure that it's saved.
