You can look on lwn.net for articles about unionfs, why its so hard and why it doesn't work very well yet (and is not yet present in Linux). Scott (ex-OLPC, a big contributor to the current /versions scheme) made some comments on IRC a few months ago that he had tried(/deployed?) unionfs for litl (in the style that you describe) and that he didn't recommend it. Still, certainly something to keep an eye on for the future. Daniel _______________________________________________ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
