man tunefs
See the -m option. This describes the fact that a certain percentage 
of the slice is withheld from writing by users. Only root can write 
to a fs once it has under the minfree percentage free. The Capacity 
output of df measures the percentage of the user-writable portion of 
the fs used. This is also briefly discussed on page 274 of the daemon 
book.

At least that is my understanding of it.
