Configuration files git repository

Good morning to you all!

I intend to create a tiny repository collecting relevant configuration and customization files I use in my YunoHost server.

What I thought about doing was creating hard links for each specific config file and placing the link inside a repository in my $HOME.

Nevertheless, I am having trouble since the permissions for such files are very different. For example, if I create a hard link for my_webapp Nginx .conf file, its owner is my_webapp user, and if I change it in the link, it changes in the original Nginx config folder, too.

Do you have any suggestions to carry out this task?
