 I agree with david. oldconfig cannot be made to fix every possible
 manual misconfiguration that has been introduced by the user, even
 those that, by chance, just worked.

 The actual Kconfig will handle pretty well the transition from
 a good config. where good is different from working-by-chance.

 There are far too many people that just keep pressing Y
 when a new kernel option appears without even considering what would
 happen or reading the help.
