Default config causes user to be unable to access the nix registry

[crazyminecuber]

First of all, good job with the project! It was easy to get working, some feedback however.

The following line in the example config in the readme

´´´
{ file = "/etc/nix/id_rsa"; parentDirectory = { mode = "u=rwx,g=,o="; }; }

´´´

causes a user running nix flake update to get the error

error: getting status of /etc/nix/registry.json: Permission denied

So I suggest changing the default config to not cause this issue? Or is there a good reason for making /nix private which I am missing?

This issue has been mentioned on NixOS Discourse. There might be relevant details there:

This is not supposed to be a default config, just an example of what's possible to do. It would be good to have a better example, though. Suggestions are welcome!

[crazyminecuber]

I think the other examples are good, but since the example with /etc/nix/id_rsa seems to break multiple subtle things, I think it should be changed/removed. The other examples show how to set permissions, so I think changing it to just /etc/nix/id_rsa would be fine. I personally have not configured any special permissions for the files field, so I do not have any good examples on hand.

The thing is that it's the only example showing how to use parentDirectory, so I wouldn't want to just remove it without a replacement. I suppose it could just be a made up secret file, though - that's pretty much what the current one is anyway. Also see #106.

I just stumbled across this.
I think the nixos wiki for this should be changed and then this can be closed, since the readme in this repo has already been changed.

Fixed by #151.

@C0D3-M4513R Since the wiki entry isn't official or affiliated with the project, I'm going to close this issue now. Feel free to copy the fix to the wiki or whatever is necessary, though.
