Its been bothering me that the 'df' command reports different values of
free space depending on whether you're logged in as the superuser.  After
reading the man pages for 'newfs' and 'tunefs' I finally understand that
10% is normally set aside for superuser use only, which accounts for the 
difference.

In the 'tunefs' documentation, it says that you can change this percentage
lower if desired, but this will reduce performance up to a factor of
three.  I'd like to set certain partitions (such as my /users partition)
so that all of it is available for anyone to use.  Is this a bad idea?
Would it really reduce performance?  I'd also like to recover part of
the 8 megs or so that are never being used in my root partition.  Does
anyone know whether this would hurt anything?  I could certainly use any
extra disk space I can find!
