我正在尝试从其启动脚本创建GCE实例图像（仅在一些设置说明之后） . 我使用命令行看起来像：
gcimagebundle -d "/dev/sda" -o "/tmp/" --log_file=/var/log/image_generation.log "--output_file_name=/tmp/myimage.tar.gz"
几秒后 gcimagebundle 退出，我收到以下错误消息（来自/var/log/image_generation.log文件）：

我尝试在手册 sudo su 之后在新实例上执行相同的启动脚本，并且一切正常 .
我从启动脚本执行 whoami ，结果是 root .
