In Linux systems, the configuration information of the mounted (Mount) file system is usually stored in the following configuration files:

1. /etc/fstab: This is The most common and primary mount configuration files. This file defines the file system that is automatically mounted when the system starts. Each line describes a mount point and the associated device, file system type, mount options, and other parameters.

2. /etc/mtab: This file is a snapshot of the currently mounted file system. It displays detailed information about all mounted file systems in the current system, including mount points, devices, file system types, and mount options. This file is automatically generated by the system and updated as the file system is mounted and unmounted.

3. /etc/exports: If you set up an NFS (Network File System) server on a Linux system, this file is used to define directories that can be shared through NFS and related permissions and options. .

4. /etc/auto.master: This file is used to configure the automatic mounting (autofs) service. It defines the top-level directory (mountpoint) for automatic mounting, and the corresponding configuration file path. Each configuration file provides detailed mounting rules and options for different mount points.

Please note that the specific configuration files may vary depending on the Linux distribution and version. The above files are common configuration files, but on some systems other configuration files or directories may exist, such as systemd mount units. In addition to configuration files, you can also use command line tools such as mount and umount to manually mount and unmount file systems.
