I see, thanks for your explanation. Gentoo people seem to build
everything for their systems, including the underlying Linux kernel.

For the installation CD, it plays a role as a temporary system to
install the real Gentoo Linux.

So there should be no default kernel configuration files. It depends
on the Gentoo user, right?
