1. A method, comprising: computing and generating a first signature from a data structure corresponding to a first computing environment, the first computing environment associated with a first version of an operating system; computing and generating a second signature from the data structure corresponding to a second computing environment, the second computing environment associated with a second version of the operating system different than the first version; comparing the first and second signatures; and responsive to a disparity between the first and second signatures, indicating an inconsistency of the data structure between the first and second computing environments.
