答え1
PXELINUX は、次の特殊パス名規則をサポートします。
::ファイル名 一般的なファイル名のプレフィックスを抑制します。つまり、「filename」文字列を変更せずにサーバーに渡します。
IPアドレス::ファイル名
(e.g. node7::filename)
一般的なファイル名のプレフィックスを抑制し、代替TFTPサーバーに要求を送信します。 IP アドレスの代わりに DNS 名を使用できます。ドットが含まれている場合は正規化されたと見なされます。それ以外の場合は、DHCPサーバー(オプション15)によって報告されたローカルドメインが追加されます。
デュアルコロン("::")は、オペレーティングシステムの使用と競合する可能性が低いために選択されました。
