behavior of "df" under root and regular user

[Jim Jagielski]

I noticed some strange behavior with "df" depending on whether it is run
by root or a regular user.

When run by root, df prints out the WRONG amount of free blocks... when run
by a regular-dude, then the free block count os correct. When root runs, df
adds back in the 10% that is used by the BSD file-system. This gives erroneous
information, since (as far as I know) this space is NOT available for file
storage...
