You may get 9.2.1 = 9.2 + updates.
This is generally fine for me. The one thing that is lost here is the possibility to go back to a certain configuration.
This might be required when doing QA, to be able to compare the behavior before/ after a bugfix.
And this might also be useful for the normal user when something gets broken by an additional update. How will the user be able e.g. to go from "9.2 + all updates until 2003-10-30 11:45 UTC" back to "9.2 + all updates until 2003-10-15 03:57 UTC"?
