I guess faster start up time because layers won't be re-extracted from the image and the "rootfs" would be in place hence faster startup times. Other use case

I guess faster start up time because layers won't be re-extracted from the image and the "rootfs" would be in place hence faster startup times. Other use case would be with stateful containers such as running a database, stopping it and starting it again without losing data (which already should be on a mounted volume) Interested to know if there are other use cases.
