我在 Debian 8 上有一个相当奇怪的问题sudo。用户无法在/etc/sudoers.d. 我使用 Chef 来分发配置，因此所有文件都是自动生成的。
例子：
此配置工作正常
root@server:~# cat /etc/sudoers.d/nginx
# This file is managed by Chef.
# Do NOT modify this file directly.
user ALL=(root) NOPASSWD:/usr/sbin/nginx
这失败了：
root@server:~# cat /etc/sudoers.d/update-rc.d
# This file is managed by Chef.
# Do NOT modify this file directly.
user ALL=(root) NOPASSWD:/usr/sbin/update-rc.d
user@www42:~$ sudo update-rc.d
[sudo] password for user:
Sorry, user user is not allowed to execute '/usr/sbin/update-rc.d' as root on server.
有什么问题？
诊断：
