question about check_disk

[Jeffrey Watts]

You have it backwards.  'df' says 24% used, not remaining.  'check_disk'
shows how much is remaining (76% and 99% in this case).  I've never liked
how check_disk displays its results by default, most Unix tools show as a
primary metric how much of a resource is used and not how much is
remaining.  It always looks wrong.
