It will find an existing config in /boot if you have one named using the upstream naming convention (which happens if you install the kernel using make install on a vanilla kernel - I'm not sure about genkernel or gentoo-sources offhand). If you have /proc/config.gz enabled then you can also do a zcat /proc/config.gz > .config to extract your current config. I always enable /proc/config.gz since it costs a few kb tops and comes in handy anytime you're not sure what config you're running (though if you built some modules after the fact it might not be entirely current). -- Rich
