Continuing the discussion from "Missing AUR Packages: grub-tools"

So if I don’t run grub-mkconfig after kernel/grub updates, will it break anything?
(= will my experience remain the same after removing this package?)

Sorry for making a new topic :sweat_smile:

  • After kernel update: no need to run the command

  • After additional kernels install: yes, you need to run the command for the new kernels to be added to Grub’s boot menu

  • After Grub, the package, update, it is recommended to run:

    1. grub-install
    2. grub-mkconfig -o /boot/grub/grub.cfg

Minor clarifications and nitpicking (:sweat_smile:):

  • after kernel install: if you want to see the installed kernel in the boot menu, then grub-mkconfig (with proper options) need to be executed
  • grub-install may require special parameters for your system in order to work properly

Thanks everybody!

What would happen if I don’t run these?

I’m on UEFI, which parameters would be need if existing?

If you have a fairly standard install then sudo grub-install --no-nvram would probably work.


Most probably nothing.

The recommendation was added to the Grub posterior to the incidence when a change upstream rendered many systems unbootable. It might not happen again, but then it might. I believe that’s kind of a safe-guarding against this possibility.
