update-grub and grub2-mkconfig commands not found

[arbitrarymahi]

I need to update the /etc/default/grub file in marinerOS but it seems it is missing. There is an open issue regarding that as well #2237

I also tried update-grub and grub-mkconfig commands but they are also not found.

sudo: update-grub: command not found

sudo: grub2-mkconfig: command not found

There is /boot/grub2/grub.cfg file present in the OS though so not sure if it's the issue with grub package or something else.

I am using ISO_2.0 from the repository dl link. https://aka.ms/mariner-2.0-x86_64-iso

With the caveat that I don't know much about this area- it looks like the grub2 package should contain /sbin/grub2-mkconfig.

I have found a fix to the problem. Actually it is missing the packages which contain grub-mkconfig
In my case installing the following resolved the error:

dnf install grub2-efi grub2-efi-modules shim

after that if update-grub command is not found you can manually create the .sh file accordingly.

Hope it helps :)
