Debian testingのnetinst CDをjigdoして焼く
いわゆる一つの備忘録．
再利用できるイメージがあればマウント
同じ作業をもう何度かやってるんだが，Jigdoは前回のイメージ作成時から変わってないパッケージを再利用してくれるので，イメージをマウントして読めるようにしてやる：
# mount -r /media/esata/images/debian/amd64-testing/debian-testing-amd64-netinst.iso /mnt/iso0
確認：
$ cd /mnt/img0 $ ls README.html README.mirrors.txt boot/ debian@ doc/ install/ pics/ README.mirrors.html README.txt css/ dists/ firmware/ md5sum.txt pool/
よかろう．
必要ファイル2個をJigdoに落とさせ，即座に開始
$ cd /tmp $ mkcd amd64-testing $ http_proxy='http://este/' jigdo-lite 'http://cdimage.debian.org/cdimage/daily-builds/daily/arch-latest/amd64/jigdo-cd/debian-testing-amd64-netinst.jigdo'
http_proxy は好みでcaching proxyであるDeleGate (at este, WinXP) にキャッシュさせてるだけなので無くても動く．
後はJigdo内での問答：

この「4」ってとこだけタイプした．やはり以前打ち込んだ内容が ~/.jigto-lite に記録されているので選ぶだけ．しかし選択肢にゴミが混じってるな... 今度きれいにしよう．

うは，一つも再利用されなかった... 前回のISOイメージは4月頭だったから，一つ残らず更新されちゃったのかな．まぁそんなこともあるだろう...

ここも初回は日本ミラーのURL http://ftp.jp.debian.org/debian/ を打ち込むんだけど，やっぱり前に打ち込んだ内容が ~/.jigdo-lite から読み込まれてデフォルト値になってるので楽ができる．単にEnterでダウンロードが開始される：

The fact that you got this far is a strong indication that `debian-testing-amd64-netinst.iso' was generated correctly.

お疲れさまでした．まぁ前回のはもう要らんだろ...

48倍 (speed=48) って速過ぎる気がするが（実測で13倍），今までとりあえずこれでしくじったことは無い．終わると -eject を付けた効果で焼かれたCD-R (DVD-R) がドライブから出てくる．ちなみに焼くのとは関係なくドライブ開けたいときにも wodim -eject と使えば役に立つ．
