What were you trying to do that didn't work?

On system with petitboot bootloader reporting version in other format than v1.X
newly installed kernel is not shown in petitboot

Please provide the package NVR for which bug is seen:

grub2-2.06-70.el9_3.1

How reproducible:

Always on a specific system

Steps to reproduce

• install a new kernel
• run grubby --default-kernel (the new kernel is reported)
• reboot

Expected results

New kernel is used

Actual results

The old kernel is used

Workaround

use grubby tool to add and remove some kernel parameter
this method should be harmless on system using BLS as well
culprit is you have to avoid using a parameter that is set already
i.e.
grubby --update-kernel $(grubby --default-kernel) --args="thisdoesnothing"
grubby --update-kernel $(grubby --default-kernel) --remove-args="thisdoesnothing"
