During `git repack -a -d` only repack objects which are loose or which reside in an active (a non-kept) pack. This allows the user to keep large packs as-is without continuous repacking and can be very helpful on large repositories. It should also help us resolve a race condition between `git repack -a -d` and the new pack store functionality in `git-receive-pack`. Kept packs are those which have a corresponding .keep file in $GIT_OBJECT_DIRECTORY/pack. That is pack-X.pack will be kept (not repacked and not deleted) if pack-X.keep exists in the same directory when `git repack -a -d` starts. Currently this feature is not documented and there is no user interface to keep an existing pack. Signed-off-by: Shawn O.
