grub2-mkconfig creates grub2-efi.cfg different from the existing one, but why?
Clash Royale CLAN TAG#URR8PPP
On Fedora 29 on a machine with UEFI hardware.
Trying to generate a new /etc/grub2-efi.cfg
.
Dry run first!
Change nothing in /etc/default/grub
.
(Actually wanted to remove rhgb quiet
from the kernel line, but tit turns out this is done by executing plymouth-set-default-theme details --rebuild-initrd
instead, see Why is Grub menu not shown when starting my computer?)
As described in Create a GRUB 2 configuration, a new file can be created by running:
grub2-mkconfig
The resulting file should go to /boot/efi/EFI/fedora/grub.cfg
and is referenced by the symlink:
/etc/grub2-efi.cfg --> ../boot/efi/EFI/fedora/grub.cfg
However, running:
grub2-mkconfig -o OUT
diff --side-by-side --width=200 /etc/grub2-efi.cfg OUT | less
...reveales a certain number of differences between the OUT
file and the original among which:
grub2-mkconfig
uses linuxefi
and initrdefi
instructions, but OUT
does not, it uses linux
and initrd
instructions. This sounds wrong!
For example:
Sounds correct in /etc/grub2-efi.cfg
:
linuxefi /vmlinuz-4.19.4-300.fc29.x86_64 ....
initrdefi /initramfs-4.19.4-300.fc29.x86_64.img
Sounds wrong in OUT
:
linux /vmlinuz-4.19.4-300.fc29.x86_64 ....
initrd /initramfs-4.19.4-300.fc29.x86_64.img
What's going on? Is there some option I forgot about? Can I replace the existing /etc/grub2-efi.cfg
?
