正常运行系统上的 Clonezilla

Question

我只在 Live USB 上使用 Clonezilla 并尝试在运行 Ubuntu 14.04 amd64 的情况下使用它，所以在以通常的方式安装它之前

apt-get install clonezilla

然后插入源USB驱动器进行克隆，以root身份启动clonezilla，选择磁盘到映像模式，然后clonezilla退出到终端并要求插入外部USB设备。我不需要将图像保存到外部 USB 磁盘，因此我只需按 Enter，然后就抛出此错误：

clonezilla 
Clonezilla mode is device-image
ocsroot device is local_dev
Preparing the mount point /home/partimag...
If you want to use USB device as a Clonezilla image repository, please\n * Insert     USB device into this machine *now*\n * Wait for about 5 secs \n * Press Enter key \nso that the OS can detect the USB device and later we can mount it as /home/partimag.
Press "Enter" to continue......
Informing the OS of partition table changes...
Mounting local dev as /home/partimag...

"Box" is an unknown partition device. Program terminated!.
Press Enter to exit...
Unable to mount resource as /home/partimag.
Are you sure you want to continue?
[y/N] 
Program terminated!

我如何在终端中定义选项而不使用不明显的clonezilla GUI？
例如，像 dd 那样： dd if=/my/source of=/my/destination conv="someoptions"
