O boot-update do Funtoo provê um mecanismo unificado para configurar os carregadores de boot GRUB 1.9x (sys-boot/grub (package not on wiki - please add)) e o GRUB 0.97 (sys-boot/grub-legacy (package not on wiki - please add)). Esse é o recomendado, o método oficial para configurar os sistemas Funtoo Linux systems para a inicialização.

Versão Atual

Man Pages

Consulte as seguintes man pages para informações detalhadas, e atualizadas em argumentos de arquivo de configuração (configuration file settings) e linha de comando (command-line):

  • boot-update(8)
  • boot.conf(5)

Inicio Rápido do GRUB 1.97+

Se utilizar o sys-boot/grub-1.97 ou mais recentes, desempenhe os seguintes passos:

  • Partition disk using GPT/GUID (recommended) or MBR partitions.
  • Install kernel/initrd to /boot
# emerge sys-boot/boot-update
# grub-install --no-floppy /dev/sda

Ensure that /etc/fstab is correct, and edit /etc/boot.conf to reflect your installation (see /etc/boot.conf.example). Then run:

# boot-update

This will auto-generate the complex /boot/grub/grub.cfg required for booting. Re-run boot-update every time your available kernels/initrds or /etc/boot.conf configuration changes.

GRUB 0.97 (grub-legacy) Quick Start

If using sys-boot/grub-legacy-0.97, perform the following steps:

  • Partition disk using MBR partitions (GPT not supported)
  • Install kernel/initrd to /boot
# emerge sys-boot/boot-update
# emerge ">=sys-boot/grub-legacy-0.97-r11"
# grub-install-legacy /dev/sda

Due to an issue with grub-legacy, you may see the following message:

# grub-install-legacy /dev/sda
The file /boot/grub-legacy/stage1 not read correctly.

Should you receive this message, you will have to install grub-legacy from the grub shell. Assuming /boot is the partition /dev/sda1 and you want to install grub to the MBR, you would run the following:

# grub-legacy
root (hd0,0)
setup (hd0)

When adjusting to fit your setup, remember 'root' is the location of your boot partition, 'setup' is where you want to install grub, and don't forget about grub's unique naming conventions for hard drives / partitions. For more information run:

# info grub-legacy

Ensure that /etc/fstab is correct, and edit /etc/boot.conf to reflect your installation. Ensure a generate grub-legacy setting in the boot section. Then run:

# boot-update

This will auto-generate the /boot/grub-legacy/grub.conf required for booting. Note that grub-legacy-0.97-r11 and later stores grub.conf in the /boot/grub-legacy directory.

Re-run boot-update every time your available kernels / initrds or /etc/boot.conf configuration changes.
