Mounting and Unmounting File Systems Objective 2.4 Devices, Linux File Systems, Filesystem Hierarchy Standard Control filesystem mounting and unmounting. Mount and unmount filesystems manually, configure filesystem mounting on bootup, configure user-mountable removable filesystems. Includes managing file /etc/. The last step required for using a file system is that it must be mounted. Mounting a file system makes it available to the system and the user. This section covers the utilities used for mounting and unmounting file systems. Also covered here are the files that contain information for file systems on a Linux system. These tools are used on a daily basis when working with Linux systems and are of particular interest when preparing to use a system and when preparing for the exam. Exam Tip
