Just a quick note about something that seems rather silly to me. I can easily export a folder to create a separate library - this is great because it'll let me easily segregate my work images from my personal images. So I exported my work folder (which contains a bunch of projects) to a network drive that's being shared via AFP from my main Linux box - no problem at all. But, when I try to open that new library, Aperture complains that it's on an "unsupported file system" and refuses to open it! If it's not going to let me open a library that exists on that file system... why the heck did it let me create it there in the first place?
