Aha. Feeling dumb that I didn't know that. Of course they're directories with some metadata. Duh. I always kinda guessed that DMGs were something like a ZIP file. Well, not really: "3. Mounting DMGs DMGs can be mounted, just like any other file system, though technically this is what is known as a "loopback" mount (i.e. a mount backed by a local file, rather than a device file)" http://newosxbook.com/DMG.html http://newosxbook.com/DMG.html Pretty cool. Thanks for the tip. Now wondering about differences between loopback mount, FUSE, potential for seamless Finder UX integration...
