Yes Jack it does. That's why you can use a "trick" with md raid 1 with metadata 0.90 or 1.0, because those both result in having two (or more) discs with ESP partitions which are readable and bootable by the EFI BIOS.
This bug thread is more about making grub-install call efibootmgr correctly to install two (or more) EFI boot entries for each of the ESP partition mirrors, than anything else. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1466150 Title: grub-install breaks when ESP is on raid To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/1466150/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
