        !            17: file system are normally created with the

        !            23: by writing on the special file
        !            24: .I special.
        !            25: The numeric size specifies the number of sectors in the file system.
        !            26: .I Mkfs
        !            27: builds a file system with a root directory and a

        !            29: directory.

        !            32: The number of i-nodes is calculated as a function of the file system size.
        !            33: No boot program is initialized by

        !            51: represents the smallest amount of disk space that will be allocated to a file.
        !            52: It must be a power of two currently selected from the range 512 to 8192.
        !            53: .B Ncpg
        !            54: specifies the number of disk cylinders per cylinder group.

        !            58: Once the file system capacity reaches this threshold, only
        !            59: the super-user is allowed to allocate disk blocks.  The default
