Description

Technical Field

[0001] The invention belongs to the field of computer technology, and in particular relates to a fully automatic generation method for a root file system of a specified operating system. Background Art

[0002] As an important part of the operating system, the root file system contains the key directories and files necessary for system startup, as well as the files necessary for mounting other file systems. Therefore, during the operating system startup process, the root file system is the first file system that must be mounted. If the operating system cannot mount the root file system from the specified device, other file systems will not be loaded correctly, and the operating system will not be able to start normally. Therefore, the root file system is crucial to the normal operation of the operating system, and its stability and reliability have a decisive impact on the operation of the entire operating system.

[0003] In traditional operating system deployment, the generation of the root file system relies on manual configuration, which is not only cumbersome and time-consuming, but also prone to errors and heavily dependent on the professional knowledge and experience of technicians. Especially on the emerging operating system platform OpenEuler, due to the immaturity of the software ecosystem and development tools, there is currently no complete support for the generation of the specified operating system root file system under the OpenEuler operating system, which makes it impossible for developers to deploy and test the root file system of OpenEuler or other operating systems under the OpenEuler operating system, which greatly restricts the expansion of the application scope of the OpenEuler operating system. In addition, the existing technology also has many shortcomings in cross-platform compatibility, automation and user-friendliness, which greatly limits the rapid deployment and wide application of the operating system root file system. Summary of the invention

[0004] In view of the above problems existing in the deployment of operating system root file systems, the present invention proposes a method for fully automatic generation of a specified operating system root file system under a Linux operating system, which can realize fully automatic generation of a specified operating system root file system under different Linux distributions.
