Without this patch, GRUB may proceed to wipe all firmware boot entries
|
||
and report a successful installation, even if efibootmgr hit an error.

Subject: Make grub-install check for errors from efibootmgr
|
||
|
||
Code is currently ignoring errors from efibootmgr, giving users
|
||
clearly bogus output like:
|
||
|
||
Setting up grub-efi-amd64 (2.02~beta3-4) ...
|
||
Installing for x86_64-efi platform.
|
||
Could not delete variable: No space left on device
|
||
Could not prepare Boot variable: No space left on device
|
||
Installation finished. No error reported.
|
||
|
||
and then potentially unbootable systems. If efibootmgr fails, grub-install
|
||
should know that and report it!
|
||
|
||
We've been using similar patch in Debian now for some time, with no ill effects.

Below is a followup to the patch above: the uninitialized variable could lead
|
||
‘grub-install’ to error out when it shouldn’t (seen on an AArch64 box where
|
||
‘grub_install_remove_efi_entries_by_distributor’ didn't have any entry to
|
||
remove):
|
||
|
||
grub-install: error: efibootmgr failed to register the boot entry: Unknown error 65535.
