This Section will give you an overview of kernels used in funtoo. Some points of interest:

  • Most Funtoo Linux kernels support the handy binary USE flag, described below.
  • Funtoo Linux offers quality kernels from other Linux Distributions, like debian-sources.
  • Advanced users may want to take a look at Additional Kernel Resources.

Overview of Kernels

No results

This is the Debian kernel, long-term stable edition and the default kernel for Funtoo Linux. These ebuilds now support the binary USE flag.


This is a more up-to-date version of the Debian kernel but it less suited for server systems.

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/debian-sources binary" >> /etc/portage/package.use
root # emerge debian-sources
root # nano -w /etc/boot.conf
root # ego boot update

Once you have a functional kernel, and want to slim things down a bit, it may be worth your time to investigate the make targets known as localmodconfig and localyesconfig to create a kernel config based on current running hardware..
