Thank you for the report.  That is a nuisance!

Your request has been considered, found useful and a new option has
been added to df to enable this format.  Please use the -P option.
That will put all of the output on one line.

  $ df -Ph /dev/mapper/VolGroup00-dati  | awk '{print $4}'

       -P, --portability
              use the POSIX output format

Please find this option already installed on your system.  I am so
glad that we could so quickly add this option for you! :-)
