Ok, how's this:

Yeah, not only is this a factor, but I also failed to take into account
another critical element. rcorder needs at least one script without any
REQUIRE lines to know where to start. Right now that's rcconf.sh by design,
but I think we need to replace that, rather than just delete rcconf.sh. This
is one of the few times when I think a dummy dependency would be useful. I
propose that I add a dummy dependency called START, and change everything
that currently depends on rcconf to depend on START instead. Sound good?
BTW, I noticed that there are several scripts that have no REQUIRE or
nostart. Should those be updated? They are: ccd, gbde, mixer, and securelevel.
