Thanks PhilK, this may be useful to me soon (but hopefully not:) ) If I do all data.fs migrations on my *nix qa box, w/ the mount points, and then straighten it all out locally, (using the same zope / plone vers., of course), then use the same method(s) @ zettai, you don't think that after I upgrade zope / plone @ zettai I'd see anything that I DIDN'T see locally, right?
Just looking for a possible sanity check.
