Description Dan Taylor 2001-02-14 11:09:47 EST
df seems to show information that does not add up. Available + used != 
total.  This seems to be more noticable the larger the drive.  /dev/sdd 
shows almost 2 gigs missing.

About 5% of the space on any normal filesystem is reserved for root, and is
not shown in the 'available' display.
