Arch Linux

Description:

I was installing Archlinux with software raid (raid1), and during the grub instalation efibootmgr failed.

I found some cross referencing:
https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/1765484
https://bugzilla.suse.com/show_bug.cgi?id=1179981

Additional info:
* package version(s): 2:2.04-8
* config and/or log files etc.
