Overview of Kernels
sys-kernel/vanilla-sources
This will install the "vanilla" (unmodified) Linux kernel sources. Current recommended version is 3.x. Funtoo Linux fully supports Linux 3.x. The advantages of this kernel include recent improvements to Linux Containers, a very modern networking stack with lots of bug fixes, and high reliability for desktops and servers. The downside is that this kernel must be manually configured by the user and does not have built-in genkernel support via the binary USE flag at this time.

This kernel tree is based on stable kernels from kernel.org with genpatches applied genpatches. Gentoo patchset aims to support the entire range of Gentoo-supported architectures. List of available genpatched kernels: genpatches-kernels

This is a RHEL6-based kernel with OpenVZ support. This kernel is now the preferred kernel for production OpenVZ deployments. It requires gcc-4.4.5 to build, which it will use automatically without the user needing to use gcc-config. We use this version of gcc since this is the version of gcc used by Red Hat to build this kernel.
sys-kernel/debian-sources
This is the Debian kernel. These ebuilds now support the binary USE flag. 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. This kernel has optional OpenVZ support, but it is much better to use openvz-rhel6-stable if you want a production-quality OpenVZ installation. For more information about how to use debian-sources and config-extract, see Using debian-sources with Genkernel below.
Binary USE
Many of the kernel ebuilds in Funtoo Linux support the very useful binary USE flag. By enabling this USE flag and emerging the kernel, the ebuild will automatically build a binary kernel image, initramfs and kernel modules and install them to /boot. The binary kernel image and initramfs can be used to boot your Funtoo Linux system without requiring any additional configuration. This is a great way to get a Funtoo Linux system up and running quickly. Here's how to do it:
root # echo "sys-kernel/openvz-rhel6-stable binary" >> /etc/portage/package.use root # emerge openvz-rhel6-stable root # nano -w /etc/boot.conf root # boot-update
