This is normal. Read the document on the 4.2 fast file system. By default, 10% of the free space on any file system is reserved to the super user. `df' hides this space, though not terribly effectively: all one need do is add up the `used' and `avail' values and note the discrepancy with `kbytes'. -- In-Real-Life: Chris Torek, Univ of MD Comp Sci Dept (+1 301 454 7690) UUCP: seismo!mimsy!chris ARPA/CSNet: chris@mimsy.umd.edu
