You could, or you could do as Garrett suggested, but what I'd likely do (have done) in the same situation is to make a new FreeBSD slice with fdisk, occupying the area you've freed above the 'doze slice, and mount it on, say, /data. Or you could mount it on say /usr/data, whatever. One caveat: if you use sysinstall to setup the fdisk/newfs/labeling of a new slice that's _before_ your boot slice, be sure to write your changes and bail out of sysinstall before it thinks you want to install there :) Cheers, Ian
