There is a real argument for keeping this and not just letting the rcNG
script do it all. Other than being a feature, the real argument goes
something like this.

If I have something plugged into "Line In" on my soundcard and I mute teh
channel, next time I reboot I will hear that "Line In" signal until the
rcNG script runs and mutes it. There is a small time period between sound
being up and the rcNG script running. If I had something constantly,  loud
and annoying connected to "Line In", that would suck.

If you really wanted to be evil, you could have the rcNG script load and
save the mixer settings from/to the loader.conf/device.hints files (or save
to another file and 'include' it somehow). Then you don't have to wait for
the rc scripts to run for the volumes to be reset.
