Abstract: An aspect of the present invention determines interface differences between different versions of an operating system. In one embodiment, the corresponding images of a first (older) version and a second (newer) version is inspected to identify whether access mechanism of a publicly accessible resource associated with a first interface provided by the first version is changed in the second version. Example of change in access mechanism includes a difference in the signature of function type resources, non-existence or change in the name or location of a file type resource and change in the physical file pointed to by a symbolic link type resource in the second version (as compared to that in the first version). A list of publicly accessible resources that are identified as having changed in the second version is then formed.
