 	  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.
