Description Ingolf Schaefer 2014-02-01 20:34:20 CET

Description of problem:
I have made an EFI-bootable version of Mageia following the instructions from the wiki  here (https://wiki.mageia.org/en/UEFI_booting). This involved manually installing grub2-efi and making the bootloader with 

grub2-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=Mageia --recheck

into the 100 MB efi partition that I mounted at /boot/efi before.

It works great with any problems, but whenever there is a new kernel, I have to manually repeat the same procedure again, since it fails to start the newer kernel from the efi boot otherwise.

How reproducible:
Each new kernel version triggers the problem.

Expected behaviour:
The post installation script should generate the efi-loader with the last configuration. That would involve mounting the efi partition as well.



Reproducible: 

Steps to Reproduce:

There should be no need to run grub2-install after a kernel update.

Kernel updates trigger a re-build of the /boot/grub2/grub.cfg which should be enough.

However I have not used EFI so I will watch this space ;)

Depending on the final approach adopted for EFI implementation in the installer then there will need to be changes to the grub2-efi %post script at least, but this will be for Mga5 I guess.

The last kernel update (3.12.9-desktop-1) worked flawlessly and is bootable after normal update without reinstalling grub2-efi.

@BarryJackson I always had a correct grub.cfg file after the update, but it would hang after booting the new kernel for whatever reason. The older kernels would start normally.

@Ingolf: Is this bug still present?
