all files on the system. The super ID is usually a member of a system-supervisor group.
The super ID has the set of special permissions called appropriate privileges. In the
Guardian environment, the structured view of the super ID, which is (255, 255), is most
commonly used; in the OSS environment, the scalar view of the super ID, which is
