File system specifier: For disk-based file system, either a device file name, a file system label specification

Mount options: A comma-separated list of options that can be used to control mount’s bahavior

Dump frequency: If the dump backup utility is used, the number in this field controls dump’s handling of the specified file system

File system check order: Controls the order in which the file system checker fsck checks the integrity of the file systems
