26 Running 'make oldconfig' within the sources directory by default uses
27 whatever config-x.y.z is the highest version available in /boot.
28 Otherwise, copying the config file desired to the sources directory
29 followed by running 'make oldconfig' will generate a new one based on
30 the config file copied.
31 You could than run the diff on the gentoo config file and the vanilla
32 one and take it from there.
