In a Linux-based architecture, what does the /mnt directory contain?

The LinuxFilesystem Hierarchy Standard (FHS), per FHS 3.0, defines directory purposes:

/mnt:Designated fortemporarily mounted filesystems, typically by system administrators.

Use: Mount points for removable media (e.g., USB drives: mount /dev/sdb1 /mnt/usb) or network shares (e.g., NFS).

Nature: Transient, user-managed, not persistent across reboots (unlike /etc/fstab mounts).

Contrast:

/media:Auto-mounts removable devices (e.g., by desktop environments like GNOME).

/mnt vs. /media:/mnt is manual, /media is system-driven.

Technical Details:

Empty by default; subdirectories (e.g., /mnt/usb) are created as needed.

Permissions: Typically root-owned (0755), requiring sudo for mounts.

Security Implications:Misconfigured /mnt mounts (e.g., world-writable) risk unauthorized access. CNSP likely covers mount security (e.g., nosuid option).

Why other options are incorrect:

B. System config/init scripts:Found in /etc (e.g., /etc/passwd, /etc/init.d).

C. Driver modules:Located in /lib/modules/.

D. Kernel state:Resides in /proc (e.g., /proc/cpuinfo).

Real-World Context:Admins mount ISOs at /mnt during server provisioning (e.g., mount -o loop image.iso /mnt).References:CNSP Official Study Guide (Linux Filesystems); FHS 3.0 Documentation.
