玄柴のセットアップ（１）KURO-RS の認識

KURO-RS 玄柴(KURO-SHEEVA)
もう２週間を切っているというのに、 オープンソースカンファレンス 2010 Kansai @ Kyoto の展示環境ができていない。

今回は 180cm 幅のブースを２コミュニティで共有する上、 別途 ShevaPlug+ が持ち込まれるので、 机の上はほとんど使わないようにしないとＰＣさえも置けなくなる。
なので、今回も、 オープンソースカンファレンス 2009 Kansai @ Kobe で展示した「壁」 を基本にしようとは思う。
ただ、上記の通り別途 ShevaPlug+ が持ち込まれるので、 神戸の時のままでは ShevaPlug がかぶってしまう。

と言うわけで、今回は玄柴ベースで出展する。

環境を整えるためのステップその１。KURO-RS の認識

カーネルのアップデート

まずは、カーネルのアップデート。 SheevaPlug の時に準じてカーネルをアップデートする。

インストーラの入手
