I'm not sure which would be simpler. Without thinking too hard on it, that seems like the appropriate solution to me, too. > 2. I don't understand what would cause that message.

Do you have alternates and are using --local? Do you have .keep packs and have set repack.packKeptObjects to false? There are other ways (e.g., an incremental repack), but I think those are the likely ones to get via "git gc". -Peff
