I know that I can use mount_mfs to construct a memory fs, but IIRC if can't allocate more memory on the end that isn't part of the file system. Has anyone any tips? (I'm sure there's a way of doing it with the vn driver, Matt?) Tnx in advance, Joe -- Josef Karthauser FreeBSD: Take the red pill and we'll show you just how Technical Manager deep the rabbit hole goes. (http://www.uk.freebsd.org) Pavilion Internet plc.
