Great, well-researched and documented post, but, unfortunately, it doesn't touch on my question... "What is /Trash all about?" No such file path exists in an OS X installation that isn't either bollixed or modified.

That question is apparently answered by tacit's post #32698 and my response in post #32700.

Thanks for the tip about ejecting v unmounting.
