Question
Which of the following is correct when talking about mount points?
Options
- AEvery existing directory can be used as a mount point.
- BOnly empty directories can be used as a mount point.
- CDirectories need to have the SetUID flag set to be used as a mount point.
- DFiles within a directory are deleted when the directory is used as a mount point.
Explanation
In Linux, any existing directory, regardless of whether it is empty, can be used as a mount point.
Common mistakes.
- B. Using an empty directory is best practice to avoid hiding existing files, but it is not a technical requirement enforced by the kernel or mount command.
- C. The SetUID permission flag has no relationship to mount point eligibility; it is used to execute files with the owner's privileges.
- D. Files inside a directory used as a mount point are not deleted; they are simply hidden while another filesystem is mounted over that directory and reappear after unmounting.
