and you can't update grub that easy in all environments

example are 4 machines i support with 4 disks as SW-RAID10 and the first 
partition /boot is a RAID1 over all 4 disks, so i need to run 
grub2-install in doubt on all 4 disks to make sure whatever one is the 
first detected in case of failures it is bootable

well, i personally take care of install grub2 on all 4 disk after i face 
the package updated, but you likely can't do that automatically in a 
safe way - so whatever config would be generated in doubt needs to work 
with whatever grub binary is in the MBR of the first found disk
