Indeed, but sadly we overlooked at the issue raised by this patch; not
the patch themselves, the move of Arch to another hosting system.

The consequence is many time-machine are now broken, for instance:

    $ guix time-machine --commit=e77412362f -- help

because this kind of snippet:

--8<---------------cut here---------------start------------->8---
       (let ((arch-patch
              (lambda (name revision hash)
                (origin
                  (method url-fetch)
                  (uri (string-append 
"https://git.archlinux.org/svntogit/packages.git";
                                      "/plain/trunk/" name 
"?h=packages/texlive-bin"
                                      "&id=" revision))
                  (file-name (string-append "texlive-bin-" name))
                  (sha256 (base32 hash)))))
             (arch-revision "418dd6f008c3d41a461353fdb60f2d73d87c58ed"))
         (append (search-patches  "texlive-bin-CVE-2018-17407.patch"
                                  "texlive-bin-luatex-poppler-compat.patch")
                 (list
                  (arch-patch "pdftex-poppler0.75.patch" arch-revision

Another story!


Well, I think this patch proposal for master can be closed.  WDYT?
