I feel it is OS (OSX bug), does not reproduce on newer 11.1 (appveyor has 10.15.7), [asked on SO](https://stackoverflow.com/questions/66103552/osx-mkdir-tmp-dir-no-such-file-or-directory-under-private-while-ls-can-l) anyways with minimalistic example. I believe it is the `tmp -> private/tmp` somehow throws it off.

<summary>But I also wonder why git-annex uses relative path for get whenever remote is specified via an absolute one?</summary>

IIRC it might have been done to minimize the path length so we have a better chance to not hit limits. But in this case, if anything - it makes it only longer, and if was actually to create a relative path, it should have not had that middle `../../../var/folders/5s/` since it is common to both:
|
||||
|
||||
```
|
||||

and if it didn't escape all the way to the `/`, mkdir would have even worked:
|
||||
```
|
||||
bash-3.2$ mkdir ../../../g225f6nd6jl4g8tshbh1ltk40000gn/T/datalad_temp_test_get_recurse_dirs7eiohcer/.git/annex/123
|
||||
bash-3.2$
|

```
|

```
