Hi everyone, I installed the latest version of the kernel among other system upgrades and I noticed it talking about adding a boot menu entry for UEFI? should I be concerned? I’m pretty sure I’m running legacy bios. Is there any additional information that would help in diagnosing this? It persisted even after after doing a timeshift and retrying the update.
Using Linux, you will have to upgrade your kernel at some point.
Continue with the update.
If you want to see if you are on legacy or not, go into the bios menu and see what it says. It has been a long time since UEFI has been standard - what is your computer?
What do you get if you execute efibootmgr in the terminal?
The text
Generating grub configuration file ...
Adding boot menu entry for UEFI Firmware Settings ...
done
comes from running grub2-mkconfig and that regardless if the system is booted in legacy mode or UEFI mode. Usually, the grub2-mkconfig is not run during kernel updates as creating the BLS files in /boot/loader/config is all that is needed to add the new kernel to the grub boot menu.

I get told “EFI variables are not supported on this system.”

I see, thank you. All I ran was dnf upgrade so I’m not sure how that happened you know?
That means your system booted in legacy bios mode. Also confirm:
hostnamectl | grep "Firmware"

it returns as “Firmware Version: P01-B1
Firmware Date: Wed 2011-04-20
Firmware Age: 14y 9month 3w 4d”
Probably some customization done in /etc/default/grub.
Ah, thank you. I’m rather new so I don’t really know all this stuff well.
Did you get to update your system succesfully?
I did, thank you for checking in. I was mostly concerned about bad actors somehow piggybacking their way in and using UEFI as a guise. I should have communicated that better, sorry. But yeah the update went fine. 
You all have been so nice, I really appreciate it.
