- 1. 概要
- 2. freedesktop を記述
- 3. カテゴリ名を日本語化
1. 概要
前ページで、ある程度まで、思い通りにはできましたが・・・。
はたと気づきました。「Manjaro」みたいにしたかったら、「Manjaro」の通りに書けばいいじゃん。
表題を「カスタマイズ」としましたが・・・正確には「パクり」ですな。
著作権の問題は気になるものの、これが一番うまくいきそうです。
2. freedesktop を記述
「root」ユーザで、ディレクトリを作成して
mkdir -pv /usr/local/share/lua/5.2/freedesktop
配下に、以下の３ファイルを作成します。
desktop.lua
init.lua
menu.lua
（以下、ディレクトリ名は適宜置き換えます）
vi /usr/local/share/lua/5.2/freedesktop/desktop.lua
下記のように記述します（うひゃ、長いですよ）。
