_I_ know that.  Tell it to whatever part of the system is trying to
load the kld.

I'm not saying that being unable to load a kld for a service that's
already compiled in is an error.  I'm saying the fact that mpd tries
to load the kld when it's already compiled in is the error.

I would go beyond "generally best" and straight into "it doesn't work".

My question is, "Is this fact documented somewhere, and I didn't see it?"
Because, if it's not, I'm going to put together a doc patch and file a PR.
