branch, which causes 2x the space to be used.
"git annex proxy" could be used to handle this.
Make it run the git command with smudge filters disabled and then
scan through the changed files in the work tree, and update pointer files
to be hard links to their content.
Make it run the git command with smudge filter set to not output content
but only pointers, and then at the end populate the pointer files, hard
when appropriate. (As an optimization, the smudge filter could also be
made to use the long-running filter interface when run this way.)
git-annex adjust and git-annex sync could both use that internally
when checking out the adjusted branch, and merging a branch into HEAD.
Or: Make the smudge filter not provide the actual file content, but the
pointer, at least when used in a checkout. And install a post-checkout
hook that populates the worktree files that were checked out.
Of course, it will also need to update the index.
Or: Make the smudge filter never provide the actual file content, but the
pointer. Install post-checkout and post-merge hooks that populate
the worktree files that were checked out. Of course, they will also
need to update the index.
A post-merge hook would also be needed to handle git pull and merge.
Problem: post-merge hook is not run when there's a merge conflict.
Git does not actually run the smudge filter in this case;
the conflicting file becomes a text file containing a merge conflict

once the merge got committed.
Problem: No hook seems to be run for git stash / git stash apply
or for git reset --hard. Fatal or can we live with needing to run a
git-annex command to populate the files after those commands?
Optionally: Use the filterdriver interface during checkout. Unfortunately that
interface is slower for cleaning during git add (see
[[todo/Long_Running_Filter_Process]]), but if the smudge filter is not
