Help with dfree command parameters

[Rohit Kumar Mehta]

Hi we use a perl script by putting the following in our smb.conf,
 
"dfree command = /etc/dfree.pl %U"

What I was wondering is whether or not we can give the script more 
information than
just the %U (username).  I would love to know the name of the share or 
its path.

The reason this information is useful is because we have some shares 
with user based
quotas and some shares (from different volumes of our XFS filesystem) 
where we want
to enforce group quotas, but not user quotas.

dfree.pl would then have to return a different amount of available space 
based on the
what resource was being accessed. 

We would be grateful for any assistance in this matter.
