==Updating grub== | |||
Sometimes there is an update for the GRUB package itself. So far, the grub package is updated, but the new GRUB Version is not automatically installed in the boot area. | |||
You can do this manually following the instructions above. Or you can install the Grub Maintainer Script ''install-grub''. It should work flawless for the majority of people, but SecureBoot, ZFS and fancy encryptions are not supported yet. | |||
{{RootCmd|command=pacman -Syu install-grub}} | |||
Then once run | |||
{{RootCmd|command=install-grub}} | |||
The package includes a hook that will reinstall the bootloader when needed from now on at every update of grub. | |||
===Additional Information=== | |||
Some things around grub can be confusing. | |||
====package version of grub==== | |||
Its the version of the grub-package present in your filesystem. But this version changing does ''not'' update the installed grub-bootloader. | |||
====grub-bootloader version==== | |||
This can only been shown while you are in the Grub menu (that won’t show up while booting by default, you need to hit [shift] during boot). Hit the key [E] and your will see the Grub version on top. | |||
====update-grub==== | |||
Does ''not'' update the installed bootloader. The ‘update’ is more about updating configuration. Think of this more as ‘applying settings’. | |||
(~ equal to grub-mkconfig -o /boot/grub/grub.cfg) | |||
===install-grub=== | |||
is the script (background maintainer) that does update the installed bootloader when you download a Stable Release/Unstable Release Version, which included a new Grub Version. | |||
