          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.
