This article introduces the basic usage of the Mount/umount command in Linux and automatic mount, the following methods are as follows:
The Mount command format is as follows:
Format: Mount [-parameters] [device name] [Mount Point]
Among the commonly used parameters are:
-A all file systems that are class-installed in the/etc/fstab file. -
F camouflage mount, make check device and directory appearance, but does not really mount file system.

1. Introduction to the System Startup Process
In Linux, each process has 4 GB space, and the kernel divides the 4 GB space into two parts. The maximum 1 GB is used by the kernel, which is called "kernel space ". The lower 3G bytes are used by each process, which is called "user space ".
After the Linux kernel is started,Init 1(Process 1) will actFirst user spaceAndroid system. The startup process can be divided into the following five stages, for example:

If you have asked experienced Linux users how to mount Disk Partitions In Ubuntu, they may tell you to use the fstab file in the/etc directory. This seems to be the only way to mount partitions in Linux, including Ubuntu. Thanks to GNOMEDiskUtility, the Mount partitions are more diversified. With this disk tool, you can easily Mount partitions in the graphic interface without modifying the fstab file in the
Mount in single-user mode
Mount-o remount in single-user mode, rw/has a major purpose
When the Linux system cannot be started, we usually need to modify some configuration files or adjust some parameters in single-user mode. However, after entering the single-user mode, our/file system is read-only and cannot be modified. Therefore, we need to use a command: mount-o remount, rw/this command is used to set the/path File System to the readable mode, which can be freely modified.
