Fedora 17 中 Sudo yum 权限被拒绝

Fedora 17 中 Sudo yum 权限被拒绝

在 Fedora 13 上，在 /etc/sudoers 中我曾经有一行：

Cmnd_Alias      SOFTWARE=/usr/bin/yum

然后对于有权限安装他/她自己的 RPM 软件包的用户，输入如下：

david          somehost=SOFTWARE

将允许他们毫无问题地运行 yum 并安装软件包。

现在，我升级到 F17，这会中断，就像在下一个示例中尝试安装“clang”包（权限被拒绝）一样。

报告的Python脚本/usr/lib64/python2.7/subprocess.py是用户可读的（有rw-r--r--）。

有什么提示吗？
