システム全体でneovim構成を使用する方法

sudoを介してのみnvimコマンドを使用したい場合は、そのままにしてください。~/.config/nvim追加の構成ファイルを作成する必要はありません。

ランニング：

sudo -E nvim /path/to/file

または：

EDITOR=nvim sudoedit /path/to/file
EDITOR=nvim sudo -e /path/to/file

からman sudo：

     -E, --preserve-env
                 Indicates to the security policy that the user wishes to preserve their existing environment variables.
                 The security policy may return an error if the user does not have permission to preserve the environment.


     -e, --edit  Edit one or more files instead of running a command.  In lieu of a path name, the string "sudoedit" is
                 used when consulting the security policy.  If the user is authorized by the policy, the following steps
                 are taken:

                 1.   Temporary copies are made of the files to be edited with the owner set to the invoking user.

                 2.   The editor specified by the policy is run to edit the temporary files.  The sudoers policy uses the
                      SUDO_EDITOR, VISUAL and EDITOR environment variables (in that order).  If none of SUDO_EDITOR, VISUAL
                      or EDITOR are set, the first program listed in the editor sudoers(5) option is used.

                 3.   If they have been modified, the temporary files are copied back to their original location and the
                      temporary versions are removed.
