@pcahyna @rmetrich
because this issue is about grub2-mkstandalone (on CentOS 8)
could you have a look here (as far as time permits)?

rmetrich commented at 2020-11-25 12:05:¶

Hi @jsmeix ,
sorry for being silent these days/months and even maybe years, I'm busy with many other things and have no time left for ReaR, unfortunately.
Anyway the issue is due to not having installed grub2-efi-x64-modules package on the system.

dcz01 commented at 2020-11-25 12:57:¶

@rmetrich Thanks a lot for your short answer.
That was the right thing we where searching for.
I installed that package on our minimal installation of CentOS 8 and it worked fine.
Now we finally got an working ISO image.

jsmeix commented at 2020-11-25 13:23:¶

Special thanks to @rmetrich
who solved this issue even with no time left for ReaR!

@rmetrich
if you can solve issues within no time,
couldn't you just spend some more no time on ReaR
and have still all time left for your many other things?
