第二次安装 rpm 时未创建符号链接
symlink not created on the second install of an rpm
这里有一些非常奇怪的东西。我正在构建一个 rpm 包，这是我的规范文件：

%doc README
奇怪的事情来了：
- 在第一次安装 RPM 时一切正常——正在 /usr/bin
中创建符号链接
- 我卸载了该工具 – 一切正常
- 我尝试第二次安装，但这次没有创建符号链接！很奇怪 ！
- 如果我重建 rpm 并再次安装它——它工作得很好，我卸载它并且再次安装它不会在第二次安装时创建符号链接。
[root@localhost rpmbuild]# rpm -e sotoolkit-1.5-1.noarch
取消链接：无法取消链接“/usr/bin/sotoolkit”：没有这样的文件或目录
警告：%postun(sotoolkit-1.5-1.noarch) scriptlet 失败，退出状态 1
[root@localhost rpmbuild]#
使用 rpmlint 检查时未发现 rpm 错误或警告
知道是什么原因造成的吗？
我发现了问题：
在 %install 部分我做错了：
ln -sf /integration/scripts/sotoolkit1.5/start.sh /usr/bin/sotoolkit
然后在 %postun 中我做错了：
unlink /usr/bin/sotoolkit
相反，正确的做法是在 %install 中：
mkdir -p %{buildroot}/usr/bin/
ln -s /integration/scripts/sotoolkit1.5/start.sh %{buildroot}/usr/bin/sotoolkit
然后将 link 添加到 %files
/usr/bin/sotoolkit
%postun 可以删除，因为 symlink 是文件的一部分，如果卸载该工具，它将被删除。
