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

Embodiment Construction

[0042] see figure 2 As shown in the physical storage structure of the Linux operating system, the main inventive point of the present invention is to reasonably tailor and configure each file constituting the Linux operating system, so that while reducing the volume, the basic functions of the operating system are retained, and at the same time It has the ability to start and run the computer directly through the operating system stored in the USB flash drive.

[0043] Specifically, in view of the problem that the Linux desktop system cannot be started from the U disk because the LILO boot program is usually used in the existing U disk used as the boot disk, the inventor added the GRUB boot program to the operating system in the U disk. GRUB (GRand Unified Bootloader) is a program that installs a boot loader into the Master Boot Record, which is the sector at the beginning of a hard disk. It allows specific commands located in the MBR to load a GRUB menu or GRUB's command env...

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...
