The new question comes before the old question in sequence. Before the questions were: 1. Do you want to install the Acme 1234 driver? 2. Do you want to install the Acme 2345 driver? After the upgrade the questions are: 0. Do you want to install any Acme drivers? 1. Do you want to install the Acme 1234 driver? 2. Do you want to install the Acme 2345 driver? So, if you answer question 0 with a no, then it sets 1/2 to a no as well. These questions come AFTER question 0, even if you had already answered them in an earlier kernel version that was missing question 0. Again, I'm not saying it is ideal. However, this is why question 0 defaults to yes. If you accidentally answer Yes for question 0 when you intended no, the only effect is asking questions 1/2, which won't actually get asked since you had previously answered them anyway. Question 0 doesn't actually change the kernel build - it just controls whether questions 1/2 get asked, and if you answer it no then it sets 1/2 to no as well. It is a design compromise so that they didn't have to rethink the entire kernel config design. -- Rich
