+From 14adc898a36948267bfe5c63b399996879e94c98 Mon Sep 17 00:00:00 2001
+From: Andreas Gruenbacher <agruenba@redhat.com>
+Date: Fri, 17 Aug 2018 14:07:31 +0200
+Subject: Switch back to syscall()
+
+Switch back to syscall() for the *xattr system calls.  The current
+mechanism of forwarding those calls to glibc breaks libraries like
+libfakeroot (fakeroot) and libasan (the gcc address sanitizer; gcc
+-fsanitize=address).
+
+Those libraries provide wrappers for functions defined in other shared
+libraries, usually glibc, do their own processing, and forward calls to
+the original symbols looke dup via dlsym(RTLD_NEXT, "symbol_name").  In
+our case, dlsym returns the libattr_*xattr wrappers.  However, when our
+wrappers try calling glibc, they end up calling the libfakeroot /
+libasan wrappers instead because those override the original symbols =>
+recursion.
+
+The libattr_*xattr wrappers will only be used when symbols are looked up
+at runtime (dlopen / dlsym).  Programs linking against libattr will
+directly use the glibc provided symbols.  Therefore, the slightly worse
+performance of syscall() won't affect any of the "normal" users of
+libattr.

-    add check for /etc/fonts/@configVersion@/fonts.conf

-/** Font configuration scheme
- - ./config-compat.patch makes fontconfig try the following root configs, in order:
-    $FONTCONFIG_FILE, /etc/fonts/${configVersion}/fonts.conf, /etc/fonts/fonts.conf
-    This is done not to override config of pre-2.11 versions (which just blow up)
-    and still use *global* font configuration at both NixOS or non-NixOS.
- - NixOS creates /etc/fonts/${configVersion}/fonts.conf link to $out/etc/fonts/fonts.conf,
-    and other modifications should go to /etc/fonts/${configVersion}/conf.d
- - See ./make-fonts-conf.xsl for config details.

-Subject: [PATCH] msgmerge: Fix behaviour of --for-msgfmt on PO files with no
- translations.
-
-Reported by Don Lawrence <dlawrence@iecok.com>
-in <https://lists.freedesktop.org/archives/p11-glue/2019-May/000700.html>
-via Daiki Ueno
-in <https://lists.gnu.org/archive/html/bug-gettext/2019-05/msg00124.html>.
-
-* gettext-tools/src/msgmerge.c (main): Treat force_po like true if for_msgfmt
-is true.
-* gettext-tools/tests/msgmerge-26: Add test of PO file with no translations.

-      GStreamer is a library for constructing graphs of media-handling
-      components.  The applications it supports range from simple
-      Ogg/Vorbis playback, audio/video streaming to complex audio
-      (mixing) and video (non-linear editing) processing.
-
-      Applications can take advantage of advances in codec and filter
-      technology transparently.  Developers can add new codecs and
-      filters by writing a simple plugin with a clean, generic
-      interface.

+commit 363c5be465dd6dde35c3d31abd7b5cca9b1f3a9f
+Author: Jan Tojnar <jtojnar@gmail.com>
+Date:   Thu Jul 23 18:49:03 2020 +0200
+
+    Improve separation between malcontent and malcontent-ui packages
+    
+    These artefacts go into both packages by default:
+    
+    * malcontent-control – a CLI tool
+    * PAM module
+    * gettext locale data
+    * help pages ✨
+    * AccountService/D-Bus interfaces
+    * Polkit com.endlessm.ParentalControls rules and policy
+    
+    Items marked with ✨ will go to ui package, while the rest is installed with the base library.
+    
+    See also the packaging done by upstream in Endless:
+    https://github.com/endlessm/malcontent/tree/5482b7eb99aee9b8c344629bc078e193d3c26ffc/debian
+    
+    Cannot upstream this since they are worried about maintainability:
+    https://gitlab.freedesktop.org/pwithnall/malcontent/merge_requests/38#note_437946

+2. From the top of the Nixpkgs tree, run
