+It's kind of backwards.  NM expects to be in control of everything by 
+default rather than to coexist with initscripts.  If it was, there'd be 
+no ifcfg files.  If it sees an ifcfg file and it contains 
+NM_CONTROLLED=NO, then it leaves the interface alone.
+
+At the time udev runs, it doesn't have any way to know that an interface 
+is controlled by NM unless someone has created an ifcfg file with 
+NM_CONTROLLED=YES.  With no file there, creating a file containing YES 
+would be useless because with no file there at all, NM will grab the 
+interface anyway.
+
+It's sort of a catch-22.  udev is assuming that ifplugd is the default 
+because on MGA3 that is true.  NM is assuming that *it* is the default 
+because that's how it was designed.
