Fstab files are familiar to everyone. During Linux Startup, each partition is mounted through the information in fstab. A typical partition entry is like this:
/Dev/sdb5/mnt/USB vfat utf8, umask = 0 0 0
/Dev/sda4 is the partition to be mounted, and sda4 is a LinuxThe name of the partition in sequence when detecting the hard disk. Generally, this name will not change, but if you have multiple hard disks and the hard disk changes in the order on your

Ii. Functions and significance of Linux UUID
Cause 1: it is the only identifier.
UUID provides a unique identifier string for the storage device in the system, regardless of the type of the device. If you add a new storage device, suc
In Ubuntu, it is found that the system uses a UUID to make a unique representation of the hard disk partition, such as:
#/DEV/SDA1#UUID =45f8-9147/media/sda1 vfat defaults,utf8,umask=000 0 1/DEV/SDA1/MEDIA/SDA1 vfat defaults,utf8,umask=000 0 1#/DEV/SDA5Uuid=5668d81168d7edad/media/sda6 ntfs-3g defaults,nls=utf8,umask=000 0 1
One advantage of doing this and using the/dev/sda5 method of direct reference part
Three ways to view the UUID of a device are summarized below:1 Command view: Blkid2 file Views: Ls-l/dev/disk/by-uuid3 Command view: VOL_ID/DEV/SDA1The role and significance of UUID1: It's really the only signThe UUID provides a unique identification string for the storage device in the system, regardless of the type of device.

Linux systems do not automatically recognize and load new devices like Windows systems, requiring manual identification and manual loading. Everything in Linux is file. The file is organized by a large file tree, and the root directory of the file tree is:/, progressively expanded from the root. These documents are spread through a number of equipment.

From the last few lines, we can see that the U disk is mounted under/dev/sdc1. Remember this mount point, which varies according to the Linux system.
