Subject: grub2: reproducible builds: embeds different strings depending on (obscure) locales

Date: Thu, 05 Aug 2021 15:11:02 -0700

[Message part 1 (text/plain, inline)]

Source: grub2
Severity: minor
Tags: patch
User: reproducible-builds@lists.alioth.debian.org
Usertags: locale

Some locales (e.g. potentially obscure locales used by reprotest) may
cause sort order issues in embedded strings in some of the grub-*.bin
binaries.


The attached patch fixes this by exporting LC_ALL=C.UTF-8 from
debian/rules.


There are still several other outstanding issues affecting the
reproducibility of grub2, but this should help reduce the differences to
troubleshoot the remaining issues.


Thanks for maintaining grub2!


live well,

Various grub-*.bin embed strings in a different order depending on
locale.
