help
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.
+ The current implementation is restricted to builds with the
+ same output directory. Many (absolute) paths are recorded in
+ intermediary files, and it is very likely that some of these
+ paths leak into the target rootfs. If you build with the
+ same O=... path, however, the result is identical.
+
This is labeled as an experimental feature, as not all
packages behave properly to ensure reproducibility.
