File 0001-mkimage-Clarify-file-alignment-in-efi-case.patch of Package grub2.24427
From 9b4c56d9b7971c2550884a78c2b4ce7ded51507d Mon Sep 17 00:00:00 2001 From: Alexander Graf <agraf@suse.de> Date: Mon, 28 Jan 2019 14:35:29 +0100 Subject: [PATCH 01/41] mkimage: Clarify file alignment in efi case There are a few spots in the PE generation code for EFI binaries that uses the section alignment rather than file alignment, even though the alignment is really only file bound. Replace those cases with the file alignment constant instead.
