推荐答案

这应该没问题。 / tmp目录由供大家使用。但要小心，这也意味着，任何人都可以阅读您的文件，如果您没有设置特定的权限！

It should be OK. /tmp is made for everyone to use. But be careful, it also means that anyone can read your files if you don't set specific permissions!

如果您不确定，让你的安装脚本检查 / tmp目录文件夹，并有可能为用户配置的另一个临时位置。这可能是因为反正不同的用户有不同的需求的最佳选择。例如，考虑与负载平衡服务器用户;她可能想使用这是她所有的主机之间共享文件夹。

If you are unsure, make your installation script check the /tmp folder and make it possible for the user to configure another temp location. This is probably the best bet anyway because different users have different needs. Consider for example a user with load-balanced servers; she might want to use a folder which is shared between all her hosts.
