[Bug 1466150] [NEW] Feature request: For EFI system grub-install should be able to install to multiple disks

[Tony Middleton]

Public bug reported:

I run a server with mirrored (RAID1) disks using grub-efi.

Root and /boot and /boot/grub are on mirrored partitions.

I have EFI partitions on both disks but it is not possible to RAID1
these as they are FAT32.  On an EFI system grub-install will only
install to one of the EFI partitions and so after running install-grub
you have to remember to copy the EFI file across.

Could grub configuration and grub-install be amended to automatically
install to multiple disks?

Searching around there seem to be many people asking this question
without any elegant solution.
