This is expected. A bundle contains a packfile, and the packfile
generation is sensitive to several things:
- the delta search is threaded (to the same number of threads as you
have CPUs). Try "git -c pack.threads=1 bundle create ...".
- we try to reuse on-disk deltas when possible. So the exact set of
packs you have (or which objects are loose) may impact the result
slightly. So between two different clones of the same repository,
I'd expect different results.
Possibly repacking first with "git -c pack.threads=1 repack -adf" might
get you an identical on-disk state in two different clones (assuming you
have the same refs and reflogs in each!).
But as you can see, we don't in general expect packfiles to be
byte-stable (this is also the reason that git clones aren't easily
resumable).
