on-any-overwrite hook, filename for smudge filter?

[Moe]

Hello git family.

I'm looking for a way to reliably preserve permissions in a repository.

I found the excellent metastore-utility[1] (which also backs etckeeper),
but it hooks into git-pull and can miss file overwrites caused by other
operations.

The closest I found to a global "on-any-file-overwrite" hook would be
the "smudge" filter-command as described in gitattributes(5).

Unfortunately the smudge-command seems to never learn
about a filename but merely filters stdin -> stdout.

The regular hooks don't cut it either, as for example the git-merge
hook doesn't run on partial merges ("XXX needs update").

So, is there a way to run a script after git has
overwritten any local file for any reason?


Best, Moe
