    There is. They are called "testing machines". 

    I interviewed at a firm that traded on a financial market in Chicago
    many years ago, and on every traders desk there were 3 machines. Two
    production machines running identical software more or less in
    parallel, and a third "testing" machine that the did the same stuff,
    only with new versions of the software. 

    Software spent 6 months in that "testing" environment before being
    rolled live. 

    While I think LVM is a really neat hammer, not everthing is a nail.
