我认为它所指的“数据”是包中的任何不可执行资源，例如/ usr / share中的东西。 你特别关心mysql或者其他的包吗？

如果数据对您有价值，您应该备份它。

因为我想打包一个ElasticSearch我需要知道什么是预期的。

如果我正确理解了你，你正在将ElasticSearch打包为.deb进行分发。

如果是这种情况，并且您正在构build一个用于公开发布的.deb包，我build议您1）完整阅读Debian Developer's Reference中关于打包的相关章节，并询问相应的Debian邮件列表（可能是Debian-Developer）。

一般来说， remove将只删除与软件包相关联的二进制文件和库，而purge将删除二进制文件，库，文档和configuration文件。 如果您的软件包没有至less通知他们，那么认为用户的数据是坏的forms。

我真的build议你在决定如何进行之前，先咨询一位经验丰富的Debian维护者 – 特别是如果你想将这个软件包提交给Debian仓库。

设备的另一个词：作为一个长期的Debian用户，几乎没有什么比第三方分发他们的软件更像一个遵循标准Debian惯例的.deb而让我恼火。 如果您想保留您的用户，请确保您的软件包保持良好并符合Debian团队制定的指导原则。
