-Until this feature is available in git annex proper, here are some small shell scripts that use [lndir](https://gitlab.freedesktop.org/xorg/util/lndir) to create a merged view of the .git/annex/objects areas of multiple git-annex repositories.
-
-* [union-link-annexes](https://chkno.net/union-link-annexes) (supports absolute paths only)
-* [union-link-annexes-with-sharp-edges](https://chkno.net/union-link-annexes-with-sharp-edges) (for relative paths when needed)
-
-Demo:
-
-    $ mkdir demo
-    $ cd demo
-
-    $ git init repo1
-    $ cd repo1
-    $ git annex init repo1
-    $ echo from1 > from1
-    $ echo both > both
-    $ git annex add from1 both
-    $ git commit -m .
-
-    $ cd ..
-    $ git clone repo1 repo2
-    $ cd repo2
-    $ echo from2 > from2
-    $ git annex add from2
-    $ git annex copy --from origin both
-    $ git annex sync
-    $ git annex list
-    here
-    |origin
-    ||
-    XX both
-    _X from1
-    X_ from2
-
-    $ cd ../repo1
-    $ git annex sync
-    $ cd ..
-
-
-    $ union-link-annexes merged \"$PWD\"/repo1 \"$PWD\"/repo2
-
