Correct.

This is already supported by the standard kernel Makefile. Try:

$ make INSTALL_MOD_PATH=/opt/eldk/<your_arch> modules_install

You  don't  build  root  file  systems  by  taking   a   full-feldged
distribution  and  removing parts. You also don't build weekend homes
by taking a mansion and removing parts.

Like a house, a root file system should be built bottom up,  starting
from  scratch and adding things you know you need. Never add anything
where you don't exactly know what it's needed for.

You can use the included SELF images as a starting point; see
