as it stands, when configuring the kernel, you can't select
initramfs capability without also selecting initrd. but isn't it
feasible that you might want initramfs and have no need for initrd?
if you make those selections independent, the help info suggests you
can save 15Kb by not having RAM

David Delaney has a proof-of-concept of an idea of his which was
presented at the last CELF, which is basically to put the kernel and
loadable kernel modules closely enough together that you can avoid the
use of long jumps. He sees a better than 1% improvement in performance,
which we've
