A while ago, I started installing Gentoo on my Xubuntu box, using a chroot from Xubuntu, following these guides: https://wiki.gentoo.org/wiki/Handbook:AMD64 http://www.wikihow.com/Install-Gentoo-Linux-from-UbuntuI decided to bootstrap my Gentoo install following instructions outlined in the Gentoo FAQ, and after some minor difficulties, I managed to succeed.Now, I'm trying to compile myself a kernel for my gentoo install, and I'm trying to go small, speedy, and minimal. I only want it to select the appropriate driver modules for the devices I have installed, but I don't know if I'll be able to get it to select those modules from the confines of a chroot.Is there a way I could generate a kernel module list in Ubuntu, then do the kernel compiling on Gentoo so it's done with my bootstrapped toolchain?
