gentoo has eclass that define default functions, so i can remove the file at build time, and it's what i'm planning to do

but first i need to solve the "install crate packages to a local index, and fill in index metadata in a way cargo doesn't cry about", and also "chromiumOS tried this but ended up with emerge spending 30 minutes on 'Resolving Dependencies'" (yes, this is portage being awful python software, but still, we need to fix it in order to do that)
