im too lazy to do the math but remember that ext2 filessytems reserve by default 5% of the filesystem for the superuser, you can see this descrepency in df on an empty filesystem where is says only 100K or such is used and yet available is 5% less then 1k-blocks. you can adjust this with tune2fs. -- Ethan Benson
