Re: Kernel Configurations


	My initial posting seems to have been misunderstood. I meant,
 *do* drop the old .config file in, so that when you re-run make
 config, the old answers would be the default. The reasons for running
 the make config again is that you catch any totally new config

	I do not think it likely that config option shall morph into
 other config option names.

	I do, in fact, regularily just drop my old .config file in,
 and just re run make menuconfig.
