+Normally localed would do an approximate parsing of the Xorg config file
+to determine the XKB keyboard layout. This doesn't make sense on Guix
+where there's no such file in /etc, and where the keyboard layout is
+known statically at configuration time.
+
+This patch removes the XOrg configuration parsing and expects to read the
+configuration from environment variables instead. It also removes the
+stateful bits that would write configuration to /etc/vconsole.conf
+and /etc/X11, which are unused in Guix anyway.
+
+Patch by Ludovic Courtès <ludo@gnu.org>.
