Yes, NFS, exported by a Netapp filer.
We was planning to export the entire

	/usr/local/mailman

but one of your hints prevent us to do this.
What exactly are the mutable directories?

Ok.

As far as mm_cfg.py must be different on each server, it prevent to
export the entire /usr/local/mailman.



Ok, thank tou very much for the hints.
