        Our mount(8) man page says under description of the
        relatively recently added "log" feature/option:

           (FFS only with UFS2 superblock layout)

        However, the newfs(8) man page does not mention the
        UFS2 text string, under description of the "-O" option
        the text says

               0    4.3BSD; This option is primarily used to build
                    root file systems that can be understood by older
                    boot ROMs.
               1    FFSv1; normal fast-filesystem (default).
               2    FFSv2; enhanced fast-filesystem (suited for more
                    than 1 Terabyte capacity, access control lists).

        Someone muttered that the UFS2 / FFSv2 confusion is something
        we have imported from elsewhere.  However, we should not
        contribute to it, and should provide for a little more smooth
        sailing when users want to enable the "log" feature.

        Inspect our mount(8) and newfs(8) man pages.
        No textual suggestion provided here.
