Computerized system and method for patching an application by separating executables and working data using different images

Systems, methods, and other embodiments associated with separating executables and working data of an application between separate images are described. In one embodiment, a method includes mounting an application image together with a working image to create an application directory for an application. The application image is read-only and includes at least an executable of the application and the working image includes working data modified by the application. The application directory provides files and paths of the files for the application together within a single unified directory while separating the executable in the application image from the working data in the working image. The method includes in response to receiving a write request to the application directory, arbitrating access to the application directory by controlling the processor to write data for the write request to the working image to maintain the working data separate from the executable of the application.
