+Subject: [PATCH 38/38] units: run ldconfig on every boot
+
+The "needs update" logic is not quite correct for CoreOS, for one it
+compares against the mtime of /usr which will match the time /usr was
+*built* not the time what /usr was updated on the system. Additionally
+it only considers moving forward, so roll backs do not work.
