Funtoo boot-update provides a unified mechanism for configuring the GRUB 1.9x (sys-boot/grub) and GRUB 0.97 (sys-boot/grub-legacy) boot loaders. It is the recommended, official way to configure Funtoo Linux systems for booting.
Contents |
[edit] Current Versions
- sys-boot/boot-update-1.6.7
[edit] Man Pages
Consult the following man pages for detailed, up-to-date information on configuration file settings and command-line arguments:
- boot-update(8)
- boot.conf(5)
[edit] GRUB 1.97+ Quick Start
If using sys-boot/grub-1.97+, perform the following steps:
- 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. 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.
[edit] 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 /dev/sda1 and you want to install grub to the MBR, you would run the following:
grub-legacy root (hd0,0) setup (hd0) quit
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 harddrives/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.
