How can the automatic unmounting file system strategy be set in Linux?

To set up the strategy of automatically unmounting file systems in a Linux system, you can achieve this by modifying the /etc/fstab file. Adding the noauto option in the file can specify that a file system will not automatically mount during system startup, thus enabling automatic unmounting.

The specific steps are as follows:

1. Open the terminal and type the following command to open the /etc/fstab file:

sudo vi /etc/fstab

1. Find the relevant line in the file for the filesystem that needs to be set for automatic unmounting, then add the “noauto” option in the fourth column of that line. For example, if you want to set the /dev/sdb1 filesystem for automatic unmounting, modify the line as follows:

/dev/sdb1 /mnt/mydisk ext4 noauto 0 0

1. Save and exit the file (in vi, press the Esc key, then input :wq to save and exit).
2. Restart the system for the automatic uninstall policy to take effect.

By following the steps above, you can set up the automatic unmounting policy for the file system in the Linux system.
