Well, the failure mode for asking about more options than are needed seems less bad than having to make another pass of config-recursive. I think my point was that we should probably document that if options are (de)selected, config-recursive should be run again, until the software is fixed. > > I've actually been looking into the ugly bits on how this can be > avoided.
