Solaris のシステム管理 (第 3 巻)

dhtadm を使用してオプションとマクロを作成するスクリプトの作成

次の例を各システムに適用して Korn シェルスクリプトを作成し、表 11-11 に一覧表示されたすべてのオプションと一部の有用なマクロを作成することができます。引用符に囲まれたすべての IP アドレスと値を、各ネットワークに関する適切な IP アドレス、サーバー名、パスに必ず変更してください。また、Vendor= キーを編集して、使用するクライアントのクラスを示す必要もあります。add_install_client -d でレポートされる情報を使用して、スクリプトを各システムに適用するのに必要なデータを取得してください。


例 11-1 オプションとマクロを追加してネットワークインストールをサポートするサンプルスクリプト

# the Ultra-1, Ultra-30, and i86 platforms. Changing -A to -M would replace
