I think we're in > agreement to pull the plug on dump. I think the only strong argument for dump/restore is that there might be some crazy^H^H^H^H^H^H dedicated hobbiests over at The Unix Historical Society who might find a 9-track tape with some 2.10 BSD backup on it, and dump/restore is format compatible with it. So _restore_ might be interesting for some of those folks. Then again, they'd probably prefer to actually restore it on their 2.10 BSD system running on a PDP-11 emulator.... so we're probably good. :-) - Ted
