Come off it, loading modules from loader.conf takes seconds off disk, out of the 2+ minute total boot up. There may be benefit on slow media, but in the general case I see no benefit (which might explain why not many people are bothering to change their working configs to save <2s on bootup). wrt to sound drivers no longer being built as modules, I wonder why this change has been made. I don't recall a mass of people complaining that they couldn't load drivers, or adding 'sound_enable="YES"' to loader.conf being particularly onerous. As has been pointed out, this change makes it hard to load/unload the snd_hda code, which is useful to wire the outputs to the appropriate pins. I suppose if we have to "boot, test, change, reboot, test change, reboot…" ad infinitum to do this in future, saving 2s on boot would be *super* useful. Whatever happened to POLA? This change surprised me, wasn't mentioned in /usr/src/UPDATING, and I still don't understand what benefits this change is supposed to bring.
