Is a possible solution something like an eselect module to indicate the preferred interface kit? It could default to any package that is available with a sequential set of preferred order. Then ebuild would consult the eselect module, and users who care can select the kit they want, and users who don't care/know get the default.
Just a nickel's worth opinion. Due to inflation it isn't 2 cents any more. -- G.Wolfe Woodbury redwo...@gmail.com
