indeed.  that's why best practices involve keeping all your partitions
relatively small and increasing their size when you need to.  so i
have a 3.0TB partition that i will bump up by 200-300GB whenver it
hits some threshold (let's say 80% or 90%, depending on rate of
growth).  

if you need to reclaim unused space, you really do have to go back to
the copy/restore techniques being discussed.

the best one is probably:

--make a new partition of the right size
--make a new fs on it
--mount it as /new
--cd /old
-- rsync -avP * /new/
