It has never failed me. You soon realise if the new kernel has significant changes from the old one (i.e. if modules have moved between sections, etc.) In that case, when you complete your make oldconfig you can fire up make menuconfig and revisit the new areas just to make double sure you haven't missed anything important. Now, doing that for the first time may be too confusing for someone who is not familiar with the process of rolling up their own kernel, therefore the handbook has to cater for the lowest common denominator and advises to go about it in a long-winded way. PS. make oldconfig is essentially the result of a diff-ing exercise between old/new kernels. Using "?" helps explain new options before you choose to select them. --=20 Regards, Mick
