If this is an NFS share, you might want to test what happens if you
set a refquota, then exceed it.  I know on OpenSolaris there have been
some bugs where you get a 'no space left on device' when you try to rm
files, in that situation, making it difficult for a user to recover
from exceeding their quota.  It's possible FreeBSD doesn't suffer from
this, but you should test it if it's likely to come up.
