[Bug-fileutils] Unsure about results of "df" program, version 4.0

[Peter Klotz]

Hi there

Here is a sample output of "df": (Sorry for the messy display)

Filesystem           1k-blocks      Used Available Use% Mounted on
/dev/hdb7              3881800   2933840    750764  80% /

/dev/hdb2              4136672   3494540    642132  84% /mnt/transfer

My question: Why do the numbers in the columns "Available" and "Used" not
sum up to the total listed under "1k-blocks"?
For example on /dev/hda there is a difference of 100000 blocks.

Thanks for spending your time, Peter.
