I had forgotten that Linus added -r when someone else had corruption in a packed object. Yea, if you use -r it may be able to resume and pick up where it left off. I haven't studied the -r code so I'm not sure how it knows where its safe to restart unpacking from. But if you have a .idx file we probably could make a really good guess based on the offsets it stores. I doubt unpack-objects makes use of the .idx. -- Shawn.
