New OpenGL management in Funtoo

Funtoo is switching to an improved system for managing multiple OpenGL providers (Mesa/Xorg, AMD and NVIDIA). The update may involve blockers and file collisions.

Introduction

This is the Debian kernel. It is roughly equal to a kernel shipped by Debian Linux in their releases. Ebuild now support the binary USE flag. The aim of this ebuild is to have support for near all possible hardware and users shouldn't really dig into configs, aka "install and forget". Daniel has added a special config-extract command which can be used to list all available official Debian kernel configurations, and generate them from the Debian files included with the kernel.

Usage

# echo "sys-kernel/debian-sources binary" >> /etc/portage/package.use
# emerge debian-sources
# nano -w /etc/boot.conf
# boot-update
Important

debian-sources with binary USE flag also automatically installing a /usr/src/linux symlink pointing to debian kernel.

Advanced use
