Using GNU GRUB 2 in Fedora
|
||
|
|
==========================
|
||
|
|
|
||
|
|
GRUB 2 provides various feature enhancements over the previous GRUB version
|
||
|
|
(referred to as "GRUB", or "GRUB Legacy") which has been unmaintained upstream
|
||
|
|
for years. GRUB has thus been deprecated in Fedora and replaced by GRUB 2 for
|
||
|
|
BIOS systems. (EFI systems still uses GRUB Legacy from the new grub-efi package.)
|
||
|
|
|
||
|
|
Utilities
|
||
|
|
---------
|
||
|
|
|
||
|
|
The GRUB 2 utilities are prefixed with 'grub2':
|
||
|
|
|
||
|
|
grub2-bin2h
|
||
|
|
grub2-editenv
|
||
|
|
grub2-fstest
|
||
|
|
grub2-install
|
||
|
|
grub2-kbdcomp
|
||
|
|
grub2-menulst2cfg
|
||
|
|
grub2-mkconfig
|
||
|
|
grub2-mkdevicemap
|
||
|
|
grub2-mkfont
|
||
|
|
grub2-mkimage
|
||
|
|
grub2-mklayout
|
||
|
|
grub2-mknetdir
|
||
|
|
grub2-mkpasswd-pbkdf2
|
||
|
|
grub2-mkrelpath
|
||
|
|
grub2-mkrescue
|
||
|
|
grub2-probe
|
||
|
|
grub2-reboot
|
||
|
|
grub2-script-check
|
||
|
|
grub2-set-default
|
||
|
|
grub2-setup
|
||
|
|
|
||
|
|
The default location for boot loader installation is /boot/grub2/ .
|
||
|
|
|
||
|
|
GRUB 2 in Fedora
|
||
|
|
----------------
|
||
|
|
|
||
|
|
The Fedora installer (anaconda) will make sure grub2 is installed for new and
|
||
|
|
updated systems. It will run grub2-install to install the boot loader in the
|
||
|
|
MBR and in /boot/grub2/, and it will write /etc/default/grub and run
|
||
|
|
grub2-mkconfig to create /boot/grub2/grub.cfg.
|
||
|
|
|
||
|
|
The active boot loader will not be changed when the GRUB 2 package is updated.
|
||
|
|
A new boot loader can be installed with something like:
|
||
|
|
|
||
|
|
grub2-install /dev/sda
|
||
|
|
|
||
|
|
grubby will patch grub.cfg (through /etc/grub2.cfg) when new kernels are
|
||
|
|
installed. The GRUB 2 configuration system in /etc/default/grub and /etc/grub.d/
|
||
|
|
is thus only used initially by anaconda, but it is possible to generate a new
|
||
|
|
grub.cfg with:
|
||
|
|
|
||
|
|
grub2-mkconfig -o /boot/grub2/grub.cfg
|
||
|
|
|
||
|
|
Documentation
|
||
|
|

|
||
|
|
|
||
|

The GRUB 2 manual can be found in grub.html or on
|
||
