This is not helpful since my whole point was not to create more places
where user overrides go.  loader.conf is blank by default, therefore it's
an easy place to put overrides for both hints and tunables.  Going and
creating two separate files that are blank by default only increases
confusion.

If David chooses to put his custom values in device.hints, he can hand
merge his changes in whenever he updates (for example, when a new driver
is imported that needs hints and GENERIC.hints is updated).  That's his
choice.  However, since loader.conf works well for overriding hints,
there's no reason for us to recommend to users that they do it this way.
That was my original point.

Wes, please change the man page to point users at loader.conf, not
device.hints.

Thanks,
