Subject: reproducibility: introduce config knob
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=71574a65e80d04db193432a7525eb49f1acdf614;p=buildroot.git

reproducibility: introduce config knob

Making the builds reproducible involves turning off build timestamps,
which some users may find annoying. So make the reproducible builds
optional.

+          This option will remove all sources of non-reproducibility
+          from the build process. For a given Buildroot configuration,
+          this allows to generate exactly identical binaries from one
+          build to the other, including on different machines.
+
+          This is labeled as an experimental feature, as not all
+          packages behave properly to ensure reproducibility.
