系统服务询问密码

Question

我正在尝试设置允许用户挂载 CIFS 共享的 systemd 服务。这是我得到的：

mount_cifs@.service

[Unit]
Description=Mount CIFS share by %i
After=network-online.target
Wants=network-online.target

[Service]
Type=oneshot
RemainAfterExit=yes
ExecStartPre=/bin/mkdir -p /mnt/dir
ExecStart=/bin/mount -t cifs //remote/path /mnt/dir -o username=%i
ExecStop=/bin/umount /mnt/dir
ExecStopPost=/bin/rmdir /mnt/dir

但是，当我运行 systemctl start mount_cifs@gncs.service 时，我收到以下消息：

Password for gncs@//remote/path: 
Broadcast message from root@ws (Wed 2016-10-26 21:24:56 CEST):

Password entry required for 'Password for gncs@//remote/path:' (PID 5677).
Please enter password with the systemd-tty-ask-password-agent tool!

我应该如何使用这个工具？

阅读后我发现pwd=$(systemd-ask-password "Password:") 至少是一种方法。现在systemd 不再抱怨了。
