Dirpref is not something which is "enabled" or "disabled", not in
the same sense as softupdates is "enabled".

Dirpref is a smarter layout of information in a partition.  You
need a version of the system which knows HOW to do that smarter
layout, and then you just rebuild the partition.  There is no
switch to turn on and off.
