-====== My Nix Configuration ======
-In order to edit the configuration without root permissions, it is convenient to symlink ''configuration.nix'' to my user's home directory, like this:
-<code>
-mkdir ~/etc
-sudo mv /etc/nixos/ ~/etc/
-sudo chown -R $(id -un):users ~/etc/nixos/
-sudo ln -s ~/etc/nixos/ /etc/
-</code>
