问题
rpm 回滚无法与最近几天创建的一组重新打包的 rpm 一起工作，但是可以与较新的 rpm 一起工作。

现在，如果我使用 -Uvvh 运行测试命令，我会收到 stderror 的调试消息，它显示 rpm 读取了 /var/spool/repackage 中的每个 rpm 文件。唯一有趣的一点是“预期大小”，但搜索后，预期大小应该有所不同，因为它按照文件系统上的格式记录文件。

我可以将这些 rpm 从重新打包目录中复制出来，如果我通过 cpio 运行它们，则可以提取文件。
我也尝试备份并重建 rpm 数据库 - 没有变化。
系统信息：
RHEL 5.8
rpm 4.4.2.3
/etc/yum.conf
tsflags=重新打包

在与 RedHat 发生纠纷后，他们确认不支持 --rollback 选项并在 RHEL 6 中将其删除。
