Hi Dan, 

The system keeps at least 5 or 10% of the total space free so that it
will always be able to find a reasonably unfragmented spot for a new
big file. That same 5 or 10% CAN be written by the root-user in
emergencies. But "root" should know it can affect the peformance of
his filesystem. Anyway, because you're still using part of the 5 - 10%
reserved-for-performance reasons, "df" will report the user-available
space as zero. 

	Roger.
