   Yup, that would be the reserved blocks to let daemons and what not   
   continue to run/log on a "full" disk.   
      
   I saw that wasted space on my video partition. Changed the reserved   
   value to about .001 and I have:   
      
   $ df /video   
   Filesystem      Size  Used Avail Use% Mounted on   
   /dev/sdb6       399G  121G  278G  31% /video   
      
      
   $ df -m  /video   
   Filesystem     1M-blocks   Used Available Use% Mounted on   
   /dev/sdb6         408550 122947    285195  31% /video   
      
   $ echo "408550 - 122947 - 285195" | bc   
   shows 408 M-blocks reserved/can't use.  :)
