In a conventional mobile terminal, a preset data source code is generally packaged into a system image file, and the system image file is burnt into a system partition of a disk, and the space of the system partition is increasingly tensed along with continuous updating of preset data. In this embodiment, the preset data source code is compiled and packaged into the preset data image file, the preset data image file is burned to the user data partition of the disk along with the user data image file, and when the mobile terminal is started, the preset data image file in the user data image file is mounted to the system directory, and because the space of the user data partition is far greater than that of the system partition, the problem of insufficient space of the system partition can be relieved.
The data of the partition of the disk cannot be directly accessed by the processor, and needs to be mounted to a mounting point to be accessed by the processor. Mounting means that the data of the partition of the disk is placed under the directory by using the directory as an entry point, and the processor can access the partition by entering the directory.
The mount point may be a directory of the root file system, and mounting the data of the partition of the disk to the directory of the root file system, thereby associating the partition with the directory, and the processor accessing the partition is equivalent to accessing the partition whenever the processor accesses the directory. The root file system is the first file system installed when the kernel is started, the image file of the kernel code is stored in the root file system, and the system boot startup program loads some initialization scripts and services into the memory to run after the root file system is installed.
Specifically, the preset data source code may be compiled and packaged into a preset data image file, the preset data image file is moved to a second user data directory, the second user data directory is packaged to obtain a user data image file, and the user data image file is burned into a user data partition of the disk.

S204, mounting the preset data mirror image file to a preset directory under a system directory for a processor to access data in the preset data mirror image file.
The system directory refers to a directory under the root file system, and is generally mainly used for mounting system image files of a system partition. In this embodiment, the preset data image file stored in the user data partition is also mounted to the preset directory under the system directory. The preset catalog refers to a subdirectory under the system catalog, is designed on the mount of the preset data mirror image file, and can be set according to practical application.
Specifically, the manner of mounting the preset data image file to the preset directory under the system directory may be: and mounting the preset data mirror image file to a preset directory under the system directory through mounting equipment. Wherein the mounting device is a dummy device that uses a file emulation block device to mount an image file. Optionally, the preset data mirror image file is firstly mounted to an empty intermediate directory through the mounting device, and then the intermediate directory containing the preset data mirror image file is mapped to the preset directory.

In one embodiment, the mounting the preset data image file to a preset directory under a system directory includes: mounting the preset data image file to an intermediate directory, wherein the intermediate directory is empty; and mapping the intermediate directory containing the preset data mirror image file to the preset directory.
In this embodiment, if the image file of the preset data is directly mounted to the preset directory under the system directory by the mounting device, the data under the preset directory may be all covered. In this embodiment, the mounting device mounts the preset data image file to the empty intermediate directory, and then maps the intermediate directory containing the preset data image file to the preset directory, so as to avoid data loss under the system directory.
The mounting device may be Loop device or the like. The intermediate directory may be used to mount the preset data image file. The intermediate directory may be a subdirectory of any directory under the root file system, such as a subdirectory of a system directory.
The mode of mapping the intermediate directory containing the preset data mirror image file to the preset directory may be: and mapping the intermediate directory containing the preset data image file to the preset directory as a subdirectory under the preset directory. That is, the intermediate directory containing the preset data image file is used as a subdirectory under the preset directory, and the original subdirectory under the preset directory is not interfered. This process may be implemented in an overridyfs manner.
