How do you think we should encode dependencies? I agree that the FreeBSD=20
way is uncentralized. However someone who studies the whole system can=20
tune it so that things get loaded in the right order (just pick the right=
set of "FIRST", "SECOND", and so on). How would we do that w/o the master=
list of values?
