+Subject: [PATCH] autotools: Add option to disable installation of systemd conf
+ files
+
+Add option to configure.ac to enable or disable install of systemd conf
+files. If --with-systemdsystemunitdir is passed to configure then the
+files will be installed to the provided directory. If the option isn't
+provided then the value is determined from the systemd pkgconfig file,
+if found in PKG_CONFIG_PATH.
+
+This change is required because Makefile.am always installed the files
+to a hard coded path that couldn't be changed.
