Subject: grub2: reproducible builds: timestamps in info pages

Date: Thu, 05 Aug 2021 14:56:43 -0700

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

Source: grub2
Severity: normal
Tags: patch
User: reproducible-builds@lists.alioth.debian.org
Usertags: timestamps
X-Debbugs-Cc: reproducible-bugs@lists.alioth.debian.org

Timestamps are embedded in the info pages shipped in grub2-common:

  https://tests.reproducible-builds.org/debian/rb-pkg/bullseye/amd64/diffoscope-results/grub2.html

  ./usr/share/info/grub.info-1.gz

  ...27·August·2022
  vs.
  ...24·July·2021


The attached patches fix this by removing the UPDATED parts from
docs/grub-dev.texi and docs/grub.texi.


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


Thanks for maintaining grub2!


live well,

Subject: [PATCH 2/3] Remove updated timestamps from grub.texi and
 grub-dev.texi

The timestamps are embedded in the documentation at build time, which
does not accurately reflect when the documentation was last updated,
and obviously causes issues for reproducible builds to embed the build
time.
