you can make it significantly smaller by editing out stuff you're not
using. typical targets are unused ethernet, video, disk drivers.
if you're not using usb or the bridge device, you can leave 'em out.
if you're not using kfs, you can get rid of that. if you're not booting
from venti, you can get rid of that. in the ip section you can get
rid of gre, rudp and likely ipmux.
i've included the kernel conf i was using for testing booting cpuf
directly from aoe storage. the kernel was "only" 2053582 bytes.
it would be about 1.5MB without the myricom driver. (large
firmware.)
