+Why Root (Superuser) is Required ?
+===================================
+
+This script must be run as root (superuser) because it performs several critical operations that require administrative privileges.
+The primary reason is the use of the **mknod** command to make device nodes (/dev/null, /dev/random, and /dev/urandom),
+which is restricted to superusers due to security considerations.
