You forgot to add your (gitignore'd) `what.foo` to git. Another `git annex add --no-check-gitignore;git commit -m \"add link\"` will make the subsequent `git annex uninit` work properly. This is also what the error message says, btw.
But there's another problem underneath: Why is `what.foo` an annex-style symlink anyway? It should just point to `example.txt`, right?
```
🐟 ❯ ln -nrs example.txt what.foo
yann in yann-desktop-nixos in …/uninit-test on  main
🐟 ❯ ls -l
lrwxrwxrwx 186 yann users 20 Nov 11:08  example.txt -> .git/annex/objects/mK/4w/SHA256E-s6--5891b5b522d5df086d0ff0b110fbd9d21bb4fc7163af34d08286a2e846f6be03.txt/SHA256E-s6--5891b5b522d5df086d0ff0b110fbd9d21bb4fc7163af34d08286a2e846f6be03.txt

```
For some reason `ln` dereferences `example.txt` before linking, resulting in `what.foo` pointing to the same as `example.txt` -- not just to `example.txt` -- causing `what.foo` to look exactly like an annex link. I thought `-n` could fix this, but it would operate on the target `what.foo`, not the source `example.txt` 🤦. I couldn't make `ln` do this properly, except for renaming/removing `example.txt`, then `ln -rsf example.txt what.foo`, then restoring `example.txt`. Not viable. A better solution is `cp -s example.txt what.foo`. That will make `what.foo` point properly to just `example.txt` and not *its* target.
BTW you can still just `git add` things like normal non-annex symlinks like `what.foo`, no need for `git annex add` here.
Also, joey prefers to have bug reports/questions and the like in either [[todo]], [[bugs]] or [[forum]], because it's clear those are the places to look through for issues. Comments below random manpages are quick to be forgotten about. 🙂
