Hi,

I have some scripts for personal automation where I use git for
backups and file synchronisation between systems.

It uses some form of tiering where large files, older files, and files
no longer present in branch heads, move to slower networked storage
and get linked via the "alternates" mechanism.

Since repacks are too expensive most of the time, I use `git
pack-redundant --all --alt-odb` to clear out "local" packs which
contents have become available in an alternate.

So since pack-redundant is nominated for removal, I would like to know
if there are any alternatives for this type of book-keeping. Of course
I can use `git show-index` and `comm` to implement similar
functionality, but using built-in facilities is less error-prone and
more efficient most of the time.

Cheers,
Mathijs
