     NNeewwllffss builds a log-structured file system on the specified special de-
     vice basing its defaults on the information in the disk label.  (Before
     running nneewwllffss the disk must be labeled using disklabel(8).)

     The following options define the general layout policies.

     --BB          The logical segment size of the file system in bytes.

     --bb _b_l_o_c_k_-_s_i_z_e
                 The block size of the file system in bytes.

     --LL          Create a log-structured file system (LFS).  This flag is cur-
                 rently required.

     --mm _f_r_e_e _s_p_a_c_e _%
                 The percentage of space reserved from normal users; the mini-
                 mum free space threshold.  The default value used is 10%.
                 See tunefs(8) for more details on how to set this option.

     --ss _s_i_z_e     The size of the file system in sectors.
