Install Guide: Install a Kernel

Install Guide, Chapter 13 < Prev Next >

Funtoo Linux stage3's include a pre-built debian-sources kernel to make installation faster and easier. To see if debian-sources is installed, type:

(chroot) # emerge -s debian-sources
[ Results for search key : debian-sources ]
[ Applications found : 1 ]

*  sys-kernel/debian-sources
      Latest version available: 3.19.3
      Latest version installed: 3.19.3
      Size of files: 81,292 kB
      Description:   Debian Sources (and optional binary kernel)
      License:       GPL-2

If a version is listed under Latest version installed, then debian-sources is already pre-built for you and you can skip the rest of the Kernel section, and proceed to the Installing a Bootloader section.


At this point it is wise to emerge latest sys-kernel/linux-firmware package, because various drivers rely on firmware blobs and instructions. Hardware like wi-fi cards, graphic cards, network cards, and others will not work properly or at all if firmware not present.

Building the Kernel

If you need to build a kernel for Funtoo Linux, please follow these steps:


See Funtoo Linux Kernels for a full list of kernels supported in Funtoo Linux. We recommend debian-sources for new users.

Let's emerge our kernel:

(chroot) # emerge debian-sources

Once emerge completes, you'll have a brand new kernel and initramfs installed to /boot, plus kernel headers installed in /usr/src/linux, and you'll be ready to configure the boot loader to load these to boot your Funtoo Linux system.


If you have a RAID in your machine, the kernel installation will pull in the mdadm tool as a dependency. It is important to edit the /etc/mdadm.conf file prior to rebooting the machine so the RAID is properly recognised and set up before the kernel attempts to mount it in the tree. Failing to do so can result in an unusable or even unbootable system! For specific details, consult the mdadm man page man mdadm or the mdadm ebuild page.


NVIDIA card users: the binary USE flag installs the Nouveau drivers which cannot be loaded at the same time as the proprietary drivers, and cannot be unloaded at runtime because of KMS. You need to blacklist it under /etc/modprobe.d/.
