Directory bindings for Linux file systems

This is a special mount method that mounts a directory to another directory.
For example, the real directory is the/etc/mount point is/mount-test



This cancels the binding.
If you unintentionally bind a used mount point to a different directory, the previous partition is also mounted on the hanging point after uninstallation. However, it is best to determine whether the mount point is occupied and cause unnecessary trouble before mounting.
