user.signingKey in git config set to SSH key path rather than a GPG key ID

[grdryn]

Describe the bug user.ssh_private_key_file property is used to populate the Git config's user.signingKey field, when that should be a GPG key rather than an SSH key.

The Git docs for this config property only mention using a GPG key, not an SSH key.

Is an SSH key path a valid value for this?

To Reproduce

1. Set ssh_private_key_file: ~/.ssh/id_rsa for a user in the fleek config
2. fleek apply
3. cat .config/git/config and see that user.signingKey is set to that value

Expected behavior I might be misunderstanding or missing how an SSH key path is a valid value for this Git config property. If not, then the behaviour I'd expect is that a GPG key ID is used for this rather than a path to an SSH key on disk.

Environment

• OS: Fedora 39 Silverblue
• Shell: bash
• fleek version: 0.10.5

TIL, it seems I was wrong and you actually can sign with an SSH key since version 2.34! I'll close this issue as it doesn't make sense now.

Just add to programs.git in user.nix the following:

signing = {
        key = lib.mkForce "your gpg key id";
        signByDefault = lib.mkForce true;
};
extraConfig = {
        gpg.format = lib.mkForce "openpgp";
};

and add lib to imports at the beginning of the file, of course.
