As I said in my original posting, this was an easy one. I think I was the only
person on this list that didn't know. I received ALOT of replies so I won't be
able to thank them all for their answers.

Original Posting:

tunefs for existing partitions.
newfs for new partitions.
Both take the -m option which will set the minfree of the partition.

NOTE: Many people warned that this will cause serious performance problems
if the % drops below 5. This is due to the way the Unix Fast Filestystem uses
the space. More research will have to be done, but as usual I got the answer
I needed.
