   * Pass --package-metadata on distros with supporting linkers (starting
     with Debian trixie and Ubuntu noble).
     The package metadata is constructed from the environment variables
-    DEB_BUILD_OS_RELEASE_ID, DEB_SOURCE, DEB_VERSION and DEB_HOST_ARCH.
+    ELF_PACKAGE_METADATA.
     Setting NO_PKG_METADATA=1 disables the generation of the package metadata.
