In the Linux operating system, the traditional application software (such as the deb and rpm packages) needs to be installed at the same time when being installed, and the traditional application software can only run on a specific operating system release. Because the out-of-core environment and the in-core version of different Linux releases are different, application software cannot run compatibly across releases, for example, software in Ubuntu 1604 cannot be installed or run normally on Ubuntu 1804 because software dependency is not satisfied. Therefore, it can be known that the current application software and the operating system are tightly coupled, the application software of a specific version can only run on the version of the specific operating system generally, and the updating and upgrading of an operating system underlying library or a certain software package can cause the unavailability of other software, which brings great challenges to third party application developers and operating system managers and also influences the improvement of the application ecology of the Linux system to a certain extent.
In order to solve the technical problems, the current mainstream method is to adopt technologies such as a virtual machine, WINE, AppImage, and flexpak, the virtual machine technology realizes system-level isolation by simulating a real computer device, and the compatible mode has large memory occupation and large performance loss. WINE translates Windows API calls into dynamic POSIX calls, and realizes the butt mapping of API interfaces between two operating systems through a compatible layer. By packaging all the dependent files of one piece of software together, the application only needs to access the internal files of the application when running, and does not need to access any files of an operating system.
