そうですか？
だってこの文のどこにもupgradeならこうするとかいう記述は
書いてありません。
実際upgrade時だろうがなんだろうが
old-prerm (if exist)-> new-preinst -> old-postrm (if exist)-> new-postinst
のように呼ばれます。

nakahara> でも簡単に score file があれば作らないというのではだめだったんですか?
post/pre-rmに削除するスクリプトを書いてしまうと
postinst時は常にscore fileがないという状態になって
しまうので単純にはいきません。
というわけでscriptを修正しなければ… -> xjump
