### Please describe the problem.
|
||||
|
||||
For shared repositories git annex refuses to move file out of repository (git annex move --to) if user triggering the move is not the owner of the file.
|
||||
|
||||
### What steps will reproduce the problem?
|
||||
|
||||
* Init two shared repositories and create a file
|
||||
* Modify that file in repo1 as user u1
|
||||
* Move the file to repo2 as "repository maintenance" user u2
|
||||
- this gives permission denied error
|
||||
|
||||
Alternatively -- mabye better understandable usecase(repository maintainer moves unused files to backup):
|
||||
|
||||
* Init two shared repositories and create a file
|
||||
* Modify that file in repo1 as user u1
|
||||
* Modify that file in repo1 a second time (regardless which user) -- this makes the version edited by u1 unused
|
||||
* Display unused files as repository maintenance user u2
|
||||
- this gives permission denied error
|
||||
* Move unused files to repo2 as "repository maintenance" user u2
|
||||
- this gives permission denied error
|
||||
