grub2-bios update on GPT disk

I have grub2 on GPT hard disk and BIOS. After grub2 update I spotted that grub2 menu screen shows an older version number than the recent one.

I run

grub_bios-install --grub-setup=/bin/true --boot-directory=/boot --no-floppy --recheck /dev/sda

and now I see the correct version number at boot up.

Does it mean that I need to run the above command every time grub2-bios gets updated? I thought core.img's only role is to load the config file and the needed modules. Are there more? I googled a bit, but I still don't understand fully how grub2 works.

Re: grub2-bios update on GPT disk

I think you do... perhaps there should be a note in the PKG about this?
