+Note that df documentation says to use the option -a to list "dummy file 
+systems".
+Which includes the binds.  Otherwise binds aren't displayed (with mga1).
+
+What happens if you use
+df --total
+Does it give the real totals of mounted devices ?
+or include the dummy file systems ?
+and also the duplication ?
+
+On mga1, with
+df -a --total
+the total includes all lines displayed.  (including binds, tmpfs, etc.)
+(Also /proc is displayed.)
+Without -a, only real partitions are displayed.
