Keep a removable-media entry in fstab.
Do not mount it at boot or through mount -a; mount it only when explicitly requested.
Which mount option should be added?
noauto excludes an fstab entry from mount -a and normal automatic processing, while the definition remains available for an explicit mount.
Detailed explanation
autoIncorrect. auto is the default behavior for automatic mounting.
noautoCorrect. noauto prevents automatic and mount -a mounting.
remountIncorrect. remount changes options on an already mounted filesystem.
bindIncorrect. bind exposes an existing directory at another path.
Try it yourself
An example you can run in a temporary verification environment.
mount --fake --all --verboseExpected result
noautoエントリが一括処理から除外される。実マウントは行わないKey points
- noauto excludes bulk processing
- The fstab entry remains
- Explicit mounting is still possible
Notes
- Environment: util-linux mount 2.39以降
- Command output formatting can vary slightly by distribution or tool version.
- Run the example in a temporary directory or process when possible.
Foundation review
Read the scope first
Check whether the command acts on the current shell, a new process, an existing process, or a file.
Verify the observable result
Use the supplied command and compare the output with the expected result.
