Try it yourself
An example you can run in a temporary verification environment.
blkid -L archiveExpected result
archiveラベルが一意なら対応デバイスパス。存在しない環境では無出力Key points

- Avoid duplicate labels
Notes
- Environment: util-linux／fstab 5
- Command output formatting can vary slightly by distribution or tool version.
- Run the example in a temporary directory or process when possible.
