+Upstream hashes both the absolute file name and the content of a file
+to derive the name for the natively compiled files. This breaks the
+staged install used in guix, as any $GUIX_PROFILE is distinct from
+the build directory. It also breaks grafts, as hardcoded store file
+names get rewritten; thus changing the file hash.
+
+In addition, this patch changes how native-comp-eln-load-path is
+constructed. Upstream, an entry of the directory “../lisp” is added
+supposedly for bootstrap only, but this directory appears to find its
+way into the actual variable despite attempts to remove it by calling
+‘startup--update-eln-cache’.
+The user-visible procedure ‘startup-redirect-eln-cache’ is kept, as
+packages may require it, but only pushes the new value now.
