You can’t use “grub2-mkconfig” to create individual boot spec entries.

Please explain how the process work, it is not so clear for me. I'm confused.
In C7 when I need to modify grub menu kernel option I modify /etc/default/grub
and run grub2-mkconfig and thats all. It always worked for me.
On C8 this does not work anymore, grub2-mkconfig is not enough, it generates
only the grub.cfg but it does not update the menu entries and need to modify
each entry using grubby. At this point what grub.cfg is used for if directives
are not loaded by it and need grubby to modify entries?
I'm missing something....
Don’t use grub2-mkconfig, it is really only for initial grub configuration. It
has a problematic past in CentOS 7 too. Disabling blscfg is possible but it
isn’t the default setup and not the recommended way of updating kernel entries.
If you need to update kernel parameters, use grubby. That’s what is run in the
kernel package install scripts (via new-kernel-package). That’s what is run in
packages like the nvidia 3rd party packages.
