+          <para>[ken] - For rust, strongly recommend installing in /opt - this
+          allows multiple versions to be used (fallback, testing a different
+          config, trying a newer version) by merely (re-)running ldconfig after
+          updating the symlink. It also prevents libraries from a previous version
+          taking up space in /usr/lib/rustlib/ (previous /opt versions can easily
+          be removed). Using a new prefix should also prevent the situation where
+          changing the config.toml (e.g. from sys llvm to shipped llvm) builds
+          fine but leaves a broken installation because cargo can no longer find
+          the matching versions of the libraries.</para>
