It's not meaningless spam. You are just failing to understand what people
are
trying to tell you.

You don't have to newfs a file system after the code was added for that
filesystem to be dirpref "enabled." If your kernel has the code in it, then
all
of your UFS file systems, even if you newfs-ed them years ago, are
dirpref-enabled.

Perhaps you should actually read the answers you've been given, instead of
dismissing them as "meaningless spam."

-------
If I had received an email like that previously I would not have dismissed
it.  Most everyone I have talked to is under the impression that you have to
newfs a drive with the kernel to enable dirpref, you are the only one I have
talked to who doesn't share this view.
