Ah, I see. --defconfig specifies the base configuration, while --configs specifies the constraints. In that case, how about --baseconfig? It might still make sense to pass --baseconfig allnoconfig or --baseconfig allyesconfig or --baseconfig randconfig, given a sufficiently complete constraints file. - Josh Triplett
