Right. Essentially df is showing storage for available file systems.
Noting that df also has a --total option, it makes sense by default
to not repeat file systems. This can be overridden easily with the
-a option as noted above.

Actually we should in fact be merging more entries!
Notice the following:

>> tmpfs                 4095336     4688   4090648   1% /run
>> tmpfs                 4095336     4688   4090648   1% /var/run
>> tmpfs                 4095336     4688   4090648   1% /var/lock

Hopefully the attached patch addresses this
(and a couple of other test issues).

thanks,
