That's one reason I always found it easier to go the other way, export /usr/{src,obj} from the build server, and do the installworld locally on the boxes in question. 's just simpler that way, when everything is in its "normal" place. -- Matthew Fuller (MF4839) | fullermd@over-yonder.net Systems/Network Administrator | http://www.over-yonder.net/~fullermd/ On the Internet, nobody can hear you scream.
