Grub.cfg changed on update?

I just ran the OS update and rebooted. I’m getting the warning that the checksums on boot/grub/grub.cfg don’t match.

I it normal for the grub.cfg file to be changed on update? Or do I need to concern myself that this is a compromise?

If it is a compromise, whats the easiest way to reset it back to its prior state?

there has been a kernel update in the PureOS Amber Repo which probably caused this PureBoot and PureOS Kernel Update to 4.19.0-9-amd64


If there is a new kernel version (being added or removed) then, yes.
