### Please describe the problem.
When I run `git annex add .` the file is no longer symlinked into the directory, but the file is keep as it is and simply added to git. This also happens with a minimalistic test repo as described below:

### What steps will reproduce the problem?
- `sudo pacman -S git-annex`
- `mkdir ./test`
- `cd test`
- `git init`
- `git annex init`
- `cp ../myLargeFile.CR2 .`
- `git annex add .`

### What version of git-annex are you using? On what operating system?
```

### Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)
It used to work before. It seem to be broken since a system update. I have tried reinstalling `git-annex` as well as all dependencies, bit without any luck.

> Added warning. [[done]] --[[Joey]]
