- Introduces a new package, grub2-x86_64-efi-bls, which includes a straightforward grubbls.efi file. This file can be copied to the EFI System Partition (ESP) along with boot fragments in the Boot Loader Specification (BLS) format * 0001-Streamline-BLS-and-improve-PCR-stability.patch - Fix crash in bli module (bsc#1226497) * 0001-bli-Fix-crash-in-get_part_uuid.patch - Rework package dependencies: grub2-common now includes common userland utilities and is required by grub2 platform packages. grub2 is now a meta package that pulls in the default platform package.

Subject: [PATCH] grub-install: remove useless check PReP partition is empty.
|
|
|
|
References: bsc#1065738
|
|
|
|
The grub-install rewrite in commit cd46aa6cefab checks that the PPeP
|
|
partition does not install an ELF binary before writing grub to it. This
|
|
causes regression in installer scripts that expect to be able to
|
|
reinstall bootloaders without first witping the partition by hand.
|
|
|
|
Fixes: cd46aa6cefab ("Rewrite grub-install, grub-mkrescue,
|
|
grub-mkstandalone and grub-mknetdir ")
