我使用元包来管理多个实验室系统中的软件和常见依赖项，到目前为止，它运行良好。但是，在最近的构建之后，当我尝试安装构建的 RPM 时，每个用于复制文件的 RPM 规范文件指令都会导致 yum 抛出事务检查错误。
构建/安装至 CentOS 7。

这构建得很好，但是当我尝试使用安装生成的 RPM 时，sudo yum install ./lab-meta-1.8.1-2EL7.x86_64.rpm收到以下错误：

Error Summary
-------------
显然我无法删除冲突的软件包，因为它们是核心系统软件包。我无法在网上或 SE 上找到任何类似的信息。我确信我只是在某个地方打错了，但我似乎找不到它。任何帮助都将不胜感激！
答案1
当您指定
%files
/usr
您正在打包/usr目录及其所有子目录。您需要更具体地打包真正属于您的包的文件和目录：
%files
/usr/share/emacs/site-lisp
/etc/cron.daily/*
等等...
