### Please describe the problem.
|
||||
|
||||
Can't find an approach to file permissions mode to get thin v6 annex repo to hold no second copies.
|
||||
|
||||
I realize that hardlinks work in such a way that all links have same permissions mode. The issue is, which mode for files I should set to always get hardlinks?
|
||||
`git-annex` seems to prefer 555 for `.git/annex/objects/` files, but appears it can create e.g. 644 when copying from remote.
|
||||
`git` remembers file modes as either 755 or 644, so after `git annex lock; git annex unlock` cycle or `git annex fix` no file is hardlinked if `.git/annex/objects/` file mode is 555.
|
||||
|
||||
### What steps will reproduce the problem?
|
||||
|
||||
* Create a new git-annex repo. v6, thin.
|
||||
* Create few files with same content but different perms (e.g. 555, 755, 644).
|
||||
* Add and commit these files to annex.
|
||||
* Observe that in this repo, 0555-mode file is hardlinked.
|
||||
* Clone this repo
|
||||
* Init annex in the second repo to also be v6 thin.
|
||||
* Fetch the annex files to second repo.
|
||||
* Observe that in the new repo, 0644-mode file is hardlinked.
|
||||
* Try to figure out which permissions to use across the repo to always have hardlinks.
|
||||
|
||||
### What version of git-annex are you using? On what operating system?
|
||||
|
||||
6.20180926. Gentoo Linux. Manually corrected ebuild based on the one in `haskell` overlay.
|
||||

||||
