Well, one has to decide between functionality and speed at times. I think it's better to have the ebuild sourced on every run instead of sourcing it only when it cache is stale. > Also, the new-foo renaming can't be reversed cleanly; consider if the > old class was kernel-mod, new class is kernels, how do you know where > to split old/new?

I like this option better than sticking another file into the public tree that no user will ever need.
