I'm sorry I made a small mistake ...

The default is 4 * fragsize, and the default fragsize is
2 KB, so the default bytes-per-inode ratio is 8 KB, not 4.

(Historically the default UFS fragsize was 1 KB with a
blocksize of 8 KB, so the default ratio was indeed 4 KB
per inode.  But that was changed quite some years ago.)
