What is a file system mount point and how is it used in the file system hierarchy?

A file system mount point is a directory in the file system hierarchy where a separate file system is attached and made accessible to the overall file system. It acts as a connection point between the file system and the operating system, allowing the operating system to access and manage the files and directories within the attached file system.

In the file system hierarchy, the mount point serves as the entry point for accessing the contents of the attached file system. When a file system is mounted at a specific directory, all the files and directories within that file system become accessible through that mount point. This means that any operations performed on the files and directories within the mount point will directly affect the attached file system.

Mount points are used to organize and manage different file systems within a single file system hierarchy. By attaching separate file systems at different mount points, administrators can effectively manage storage resources and control access to specific areas of the file system. This allows for better organization, scalability, and flexibility in managing large amounts of data.

Mount points also enable the mounting of remote file systems, such as network-attached storage (NAS) or distributed file systems. By specifying the mount point as a remote location, the operating system can access and interact with files and directories stored on remote servers as if they were part of the local file system.

Overall, file system mount points play a crucial role in the file system hierarchy by providing a means to attach and access separate file systems, enabling efficient storage management and facilitating remote file access.
