O tarball com o estágio 3 de Funtoo Linux inclui um kernel pré compilado chamado de debian-sources. Isso torna a instalação mais rápida e fácil. Para ver qual versão do debian-sources está instalada, digite:

(chroot) # emerge -s debian-sources

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

Se a versão mais recente for igual a versão já instalada, o kernel debian-sources já estará pré compilado e você poderá pular o restante da seção Kernel e prosseguir para a seção Instalando um Gerenciador de Arranque.

   Important

Neste ponto, é aconselhável emergir o mais recente pacote sys-kernel/linux-firmware, porque alguns drivers contam com binários (blobs) e com arquivos de firmware. Hardware como: cartões wi-fi, placas gráficas, placas de rede e outros, não funcionarão corretamente se o firmware relacionado não estiver presente.

Construindo o Kernel

Se deseja construir seu próprio kernel, por favor siga os passos seguintes:

   Note

Veja Funtoo Linux Kernels para uma lista completa dos kernels suportados em Funtoo Linux. Recomendamos debian-sources para usuários novatos .

   Important

debian-sources with binary USE flag requires at least 20GB free in /var/tmp and takes around 1 hour to build on a Intel Core i7 Processor.

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.

   Warning

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.

   Note

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/.

   Note

For an overview of other kernel options for Funtoo Linux, see Funtoo Linux Kernels. There may be modules that the Debian kernel doesn't include, a situation where genkernel would be useful. Also be sure to see hardware compatibility information.
