I don't think users can create sub-FS, although it seems to be possible to allow jails. chflags nodump is not privileged, but not supported with NFS and can easily lost by many type of applications, which unlink/open files for writing. .something files holding filter rules work in all cases. -- B.Walter http://www.bwct.de http://www.fizon.de bernd@bwct.de info@bwct.de support@fizon.de
