+
+    mount: don't propagate errors from mount_setup_unit() further up
+    
+    If we can't process a specific line in /proc/self/mountinfo we should
+    log about it (which we do), but this should not affect other lines, nor
+    further processing of mount units. Let's keep these failures local.
+    
+    Fixes: #10874
