Using GNU GRUB 2 in openSUSE
|
||||
============================
|
||||
|
||||
Though GRUB 2 provides various feature enhancements over previous GRUB
|
||||
version (referred to as "GRUB", or "GRUB Legacy"), it did not reach its
|
||||
stability and feature completness yet, and thus is not ready to replace
|
||||
it for the whole user base. This package is primarily intended to
|
||||
encourage testing and accelerate distribution integration.
|
||||
|
||||
It is generally safe to install the package. It is able to co-exist with
|
||||
existing GRUB installation and adds itself to the GRUB menu upon
|
||||
installation, so you'll able to select GRUB 2 from GRUB menu during
|
||||
the boot.
|
||||
|
||||
Utilities
|
||||
---------
|
||||
|
||||
The GRUB 2 utilities are prefixed (or postfixed) with 'grub2':
|
||||
|
||||
grub2-editenv
|
||||
grub2-mkimage
|
||||
grub2-mkelfimage
|
||||
grub2-mkrescue
|
||||
grub2-emu
|
||||
grub2-install
|
||||
grub2-mkdevicemap
|
||||
grub2-probe
|
||||
grub2-setup
|
||||
update-grub2
|
||||
|
||||
Documentation
|
||||
-------------
|
||||
|
||||
The GRUB 2 lacks documentation. While you are encouraged to contribute
|
||||
the documentation, you can use the GRUB 2 Wiki [1] as primary source of
|
||||
information pertaining to this development snapshot.
|
||||
|
||||
[1] http://grub.enbug.org/
|
||||
|
||||
If you intend to install grub2 as your primary boot loader refer to
|
||||
the GRUB 2 Wiki for information on how to set it up.
|
||||
|
||||
Support channels
|
||||
----------------
|
||||
|
||||
If you find a bug in this package, report them to the openSUSE Bugzilla [2].
|
||||
|
||||

|
||||
|
||||
Installation
|
||||
------------
|
||||
|
||||
There is not yet any support in openSUSE to configure and install
|
||||
grub2. To install it for the first time, run (replace /dev/sdaX with
|
||||
your boot partition or use /dev/sda for the MBR):
|
||||
|
||||
# grub2-install --no-floppy /dev/sdaX
|
||||
# grub2-mkconfig -o /boot/grub2/grub.cfg
|
||||
|
||||
To just update the configuration after the kernel changes, run
|
||||
# grub2-mkconfig -o /boot/grub2/grub.cfg
|
||||
|
||||
For testing, you might want to pass --grub-setup=/bin/true to
|
||||
grub2-install - this way, grub2 is not setup in the MBR and you can
|
||||
use grub to chainload a grub2 configuration.
|
||||
|
||||
In the grub menu.lst, just add (after changing the hd0,1 parameter):
|
||||
title GNU GRUB 2 -- openSUSE 12.1 - GNU GRUB 2
|
||||
kernel (hd0,1)/boot/grub2/core.img
|
||||
|
||||
Warning
|
||||
-------
|
||||
Currently, perl-Bootloader does not support grub2 as bootloader.
|
||||
|
||||
Therefore you need to run the following after each kernel change:
|
||||
# grub2-mkconfig -o /boot/grub2/grub.cfg
