Why does ECS create a custom image to create a server that requires comment mounts

When creating an ECS instance with a custom image, mounting the disk fails for the following reasons:

When the instance is started, the disk is mounted according to the settings in the fstab file, but the mount fails because there is no partition:

There is no need to comment on disk mounting. Generally, a data disk is selected when the server is created, and the data disk is generated from a snapshot of a data disk that has been partitioned and formatted.
