Hi,

I have installed Debian Stretch on my first system using UEFI. I used a 
two disk Raid 1 + LVM configured during install time to mount / on 
(among other things).

But now I need to figure out how to add redundancy to the software raid 
1 since I believe boot entries are only added to one disk during 
installation time?  According to 
https://wiki.debian.org/UEFI#Missing_features there doesn't seem to be 
much options. Is my only option to copy the FAT32 EFI system partition 
from the first disk to the second disk and then use efibootmgr to add it 
(the second disk) as a boot entry? And will any subsequent kernel or 
grub updates affect the system partition and thus require another 
copy/sync to the second disk?

Regards,
