Hence my Looks more like an opinion. In fact, I work on a modularized kernel config which I want to commit to -current at some point (for those which do not care how long it takes to boot the system). The goal of my work is to produce something like GENERIC+more, just as much as possible loaded as kld's (the "+more" part is the result of a poll I did on stable@, it contains only stuff which can not be loaded as a kld, and I provide a loader.conf which disables the parts which would cause a major change in behavior). Currently I'm doing some compile testing, I should be able to provide something for review soon (on current@).
