            Bug ID: 277739
           Summary: makefs creates UFS filesystem that fsck considers
                    invalid
           Product: Base System
           Version: 14.0-STABLE
          Hardware: Any
                OS: Any

I used makefs to create a UFS filesystem.  The filesystem is marked clean but
fsck reports errors.
