Package: gummiboot Version: 45-2 Severity: wishlist Tags: patch It would be nice if gummiboot would support installing its EFI loader to multiple EFI system partitions in order to gain failsafe support for RAID setups under UEFI. The attached patch allows (optionally) configuring multiple targets via GUMMIBOOT_EFI.

Installing the patched gummiboot and configuring
/etc/default/gummiboot:
$ grep -v -e ^$ -e ^\# /etc/default/gummiboot
GUMMIBOOT_EFI="/boot/efi /boot/efi1"
GUMMIBOOT_ROOT="/dev/mapper/vg--efi-debian64"
GUMMIBOOT_OPTIONS="ro quiet systemd.show_status=1"
Installing gummiboot to both EFI system partitions:
# gummiboot install --path="/boot/efi"
# gummiboot install --path="/boot/efi1"
# update-gummiboot
setting up efibootmgr:
# efibootmgr -c -d /dev/sda -p 1 -l /EFI/Boot/Bootx64.efi -L "gummiboot-primary"
# efibootmgr -c -d /dev/sdb -p 1 -l /EFI/Boot/Bootx64.efi -L
"gummiboot-secondary"
# efibootmgr -v

Subject: [PATCH 2/2] allow using multiple target locations for $GUMMIBOOT_EFI
This is useful for keeping multiple EFI system partitions in sync,
e.g. for a RAID setup using multiple disks. The EFI system partitions
must not be on the RAID array itself.
With this patch, it's possible to configure this in
/etc/default/gummiboot using this syntax:
GUMMIBOOT_EFI="/boot/efi /boot/efi1"
As before, gummiboot and efibootmgr need to be installed manually.
