Method for implementing Linux operating system being suitable for mobile application

Abstract

The invention discloses a realization method of Linux operation system suitable for mobile application, which comprises (1), in an operating system, using a GRUB guide program to process system guide, (2), starting in core, at the initialization of operating system, adding a mobile memory device support and hanging a root file system, (3), compressing the files of the operating system and storing the compressed files in mobile storage devices as U disk or USB key or the like. Via the invention, user can only bring a U disk storing the Linux operating system but not portable computer in outdoor condition. When in use, user only needs to connect the U disk with one computer, which can normally operate without hard disk on the connected computer.

Description

technical field [0001] The invention relates to a method for realizing a Linux operating system, in particular to a method for realizing a Linux operating system stored in a mobile memory, connected to a host at any time, and directly starting the system from the mobile memory, belonging to the technical field of computer operating systems. Background technique [0002] Linux is an open source operating system. Compared with the current Windows operating system, it has many advantages such as low cost, low resource usage, and suitable for high-performance computing. In addition, it has good scalability and scalability. Maintainability, so it is generally welcomed by users and programmers. [0003] The Linux operating system stores related files in the form of a directory tree. Figure 1 shows the file system structure of a typical Linux system. Under the root directory, include / bin, / etc, / boot, / dev, / home, / lib, / mnt, / root, / sbin, / tmp, / usr, / var and other folders. Amo...

AI Technical Summary

Problems solved by technology

However, the above-mentioned existing Live CD versions generally have very weak support for USB storage devices. For example, in some versions, after the system starts up, it must wait for the root file system to be mounted, and then detect whether there is a USB storage device on the USB interface according to the hardware. Storage devices to determine whether to add USB storage device support

According to such execution logic, if the root file system is not mounted, the support for USB storage devices cannot be added, which logically forms a deadlock state, causing the system to fail to start at all.

[0006] On the other hand, in the existing mainstream Linux operating system, if you want to make it have complete functions, the space required for installation is more than 1.8G, and the existing mainstream USB mobile storage devices such as U disk, etc., its capacity is mostly Within 1G, the next complete version of the Linux desktop operating system cannot be installed at all

Although the Linux operating system has the characteristics of easy tailoring of the kernel, such tailoring will inevitably lead to the loss of corresponding functions, so that it cannot fully meet the needs of ordinary users.
