OK, thought I would start playing with this... Figured I would load a separate site to start with . It fails, claiming it cant load oid. The site is orignally on 2.1.6, if it matters. Then I copied the current Data,fs to foo.fs, and figured I'd give it a try, being a new .fs and all. It complains about duplicate ids. What am I missing? I can copy Data.fs.in to a new name, and mount it fine.
