22/// Provide emergency recovery tools for damaged or unrecoverable filesystems.
23/// These operations are potentially dangerous and should only be used when
24/// the filesystem cannot be mounted or accessed through normal means.
25/// Most rescue operations require CAP_SYS_ADMIN and an unmounted filesystem.
