mmm, well if it has already been installed , why would you ever have to
run grub-2-install again?? all you would have to do is modify the
grub.cfg whenever you add a new kernel.. I guess the only way to test
would be to add/remove a kernel, then JUST run grub2-mkconfig, reboot &
see if the changes were updated..
or am I missing the point..
Hello,
In my opinion, it odes not matter.
after grub-install /dev/sda
grub knows that it has to read the file
/boot/grub2/grub.cfg
Then you can change it, it will use the chnaged file.
There is no copy of the copy in /dev/sdx
