+        Since a user can be be specified both by username as well as one or 
+        more usergroups, it is possible that several configuration lines 
+        enable that user to create network interfaces. In such cases, any 
+        interfaces create are counted towards the quotas of the user or group 
+        in the order in which they appear in the file. If the quota of one 
+        line is full, the rest will be parsed until one is found or the end of 
+        the file.
