RAID + UEFI

[Thomas Kloepfer]

Hello Justin,

thanks for the quick answer.

I tried to use your disk_config. And I get a a raid as expected.
But the script for settign up grup [ config/scipts/GRUP_EFI/10-setup ] 
fails.
Hence I end up with a system tha can not boot.

What I find in [ scripts.log ]:
-------------------------------
=====   shell: GRUB_EFI/10-setup   =====
...
+ echo Install grub on /dev/sda
+ unshare --pid --fork --kill-child
    --mount-proc chroot /target grub-install
    --no-floppy --force-extra-removable /dev/sda
Installing for x86_64-efi platform.
grub-install: error: disk `md0' not found.
++ error=1
...
Install grub on /dev/sdb
+ unshare --pid --fork --kill-child
   --mount-proc chroot /target grub-install
   --no-floppy --force-extra-removable /dev/sdb
Installing for x86_64-efi platform.
grub-install: error: disk `md0' not found.
++ error=1
...
done
+ exit 1
GRUB_EFI/10-setup    FAILED with exit code 1.
-------------------------------

So my question is: Have you twaked [ GRUP_EFI/10-setup ] ?
How can I fix this error?
Why is the script telling me it uses [sda] for installation bun then 
trying [md0]?

Perhaps some of the envirenment-variables might help, so I list a few:
FAI_VERSION=6.0.5
disklist='sda sdb '
