       To remove the existing package:

         nix profile remove path:${flake1Dir}

       The new package can also be installed next to the existing one by assigning a different priority.
       The conflicting packages have a priority of 5.
       To prioritise the new package:

         nix profile install path:${flake2Dir} --priority 4

         nix profile install path:${flake2Dir} --priority 6
