从旧的 Ubuntu 安装中恢复 encryptfs 卷

我有一些 encryptfs 系统的备份。我确信它们没有有用的数据，但我想试验一下如何恢复它们。

我没有长期恢复密钥，因为当需要时谁又真正拥有它们呢？

我确实对我当时的登录密码有一些很好的猜测，但我真的找不到针对这种情况的良好指南。

第一个问题是关于术语的。从文档中，我不确定什么映射到登录密码、恢复密钥、Private.sig、包装的密码、未包装的密码...

第二个问题是，Ubuntu 10.04 中这些问题的默认设置是什么？我问这个问题是因为我当前的流程是：

  1. 安装-t ecryptfs.Private/测试
  2. ls /测试
  3. 查看错误文件
  4. 卸载/测试
  5. 重复另一次密码猜测

这可能是因为这里的值错误而失败，不一定是因为我输入了错误的登录密码。
