 Okay, it's now clearer.  A few more small points:

 - I'd replace "data source file" with "data source" because "data
   source" is a more abstract notion that a concrete "file"
 - Similarly, I'd simply say "backend" instead of "backend file".

 Something like this: "The administrator doesn't have to do anything
 for b10-auth to serve the new version of zone except for the
 configuration such as the one described in <reference to
 in-memory-datasource-with-sqlite3-backend>".

 But I'd leave it to you.  Please feel free to merge with addressing
 the above two points.
