Expanding / is not something I'd recommend from a policy perspective.

What you are asking for is easily accomplished with LVM ... included in
the most recent versions of RedHat. It lets you grow (or shrink) volumes
and filesystems as your storage requirements and resources change.

EVMS (http://evms.sourceforge.net/) takes this concept to the next level
with really cool tools.
