Ah, gotcha.

Oh I'm being additive here. You'll have feature profiles for the stuff
we talk above and distro profiles which solve Linus' issue. Basically
one coarse-grained config option will either select a feature which has
a lot of small subfeatures of which some are sane and want to be enabled
by default when selecting the topfeature.

Or a distro-specific feature which could itself select other
topfeatures.

I haven't tried this in reality to actually be able to say that a
tree-like configure approach would actually make sense and work. It
sounds like a nice idea though, especially having the hierarchical
structure. :)
