    1. こんばんは。aptitude のメンテナをやっているものなのでちょっと気になった点についてコメントです。「aptitudeは(/var/log/aptitudeのログを元に)不要になったパッケージも削除します」は嘘ですよ。/var/lib/apt/extended_states というデータベースがあり、依存関係で引き込まれて自動的にインストールされたか否かに関する情報がそこに含まれています。ログなんて飾りですよ。何ヶ月かすれば logrotate に消されてしまうものなので。;-) - Posted by noritada at 2008年01月10日 03:22
    1. ptitudeのメンテナさん直々に指摘していただけるなんて光栄です。ちゃんと確認もせずにふわふわな状態で嘘を書いてしまってすみません……。aptitude も(/var/lib/aptitude/pkgstatesだけでなく)/var/lib/apt/extended_statesを読み込んでくれるんですね。てことは、この二つを混用することによる問題って何が原因で起こるのでしょう。というか、問題自体も解決済みなのかな。やっぱちゃんと確認してからって話になっちゃいますね……。 - Posted by しぐま at 2008年01月11日 21:27
