原因

这个 tar 包是在 macOS 上创建的。macOS 使用 libarchive（bsdtar）创建归档文件时，会把 macOS 特有的**扩展属性（extended attributes）**也打包进去，尤其是 com.apple.quarantine——这是 macOS 在文件从网络下载后自动添加的隔离标记。

当你用 Linux 上的 GNU tar 解压时，它不认识这些 macOS 特有的 PAX 扩展头关键字，所以打印了警告信息：

tar: Ignoring unknown extended header keyword 'LIBARCHIVE.xattr.com.apple.quarantine'

影响

完全没影响。GNU tar 会忽略未知的扩展头，文件内容正常解压，功能不受任何影响。
