What version of RPM are you using? If you're using a newer one, I have a trick that might work for you.
Newer versions of RPM have a transaction safe rollback option; simply use the --repackage command, and it'll generate a package that includes all the idiosyncratic crap of the original install. Mind you, you'll have to actually DO something (e.g rpm -e --repackage rpm_goes_here which will ERASE the original, while making a package which you SHOULD be able to restore (after you've made a copy), but if you expect this to work perfectly, I have a BRIDGE you might want to buy), so it's a bit of a leap of faith if you don't have a full backup.
There is some configuration involved, and you need to test test test before you try this on something critical, but this may work.
You will have to use the rpm -q --queryformat "" to get the header from the already installed rpm. Eg. rpm -q --queryformat "Release: %{RELEASE}\n" installed_rpm
For getting the files to fill the %files Section use the rpm -ql command.
2] run rpmbuild -bb specfile to generate the rpm file.
A deltarpm contains the difference between an old and a new version of a rpm, which makes it possible to recreate the new rpm from the deltarpm and the old one. You don't have to have a copy of the old rpm, deltarpms can also work with installed rpms.

您使用什么版本的 RPM？如果您使用的是较新的产品，我有一个可能对您有用的技巧。
较新版本的 RPM 有一个事务安全回滚选项；只需使用 --repackage 命令，它就会生成一个包，其中包含原始安装的所有特殊垃圾。请注意，您实际上必须做一些事情（例如 rpm -e --repackage rpm_goes_here 这将删除原始文件，同时制作一个您应该能够恢复的软件包（在您制作了副本之后），但是如果您期望它能完美地工作，我有一个你可能想买的桥），所以如果你没有完整的备份，这有点信仰的飞跃。
涉及一些配置，您需要先进行测试测试，然后再对关键的内容进行尝试，但这可能会起作用。

基本上，您必须执行以下操作：
1] 创建一个包含所有标头的 .spec 文件 [ http://www.rpm.org/max-rpm/s1-rpm-build-creating-spec-file.html ]
您必须使用 rpm -q --queryformat "" 从已安装的 rpm 中获取标头。
例如。
rpm -q --queryformat "Release: %{RELEASE}\n"installed_rpm要获取文件填充
%files部分，请使用rpm -ql < /代码> 命令。2]运行
rpmbuild -bb specfile生成rpm文件。Basically you will have to do the following:
1] Create a .spec file with all the headers [ http://www.rpm.org/max-rpm/s1-rpm-build-creating-spec-file.html ]
You will have to use the rpm -q --queryformat "" to get the header from the already installed rpm.
Eg.
rpm -q --queryformat "Release: %{RELEASE}\n" installed_rpmFor getting the files to fill the
%filesSection use therpm -qlcommand.2] run
rpmbuild -bb specfileto generate the rpm file.重新创建 RPM 的最佳方法是从源 RPM 中进行。很棒的教程这里。
Best way to recreate an RPM, is to do it from the source RPM. Great tutorial here.
deltarpm 包可以做到这一点：
The deltarpm package can do that:
