finishes executing, similar to a tmpfs mount point being unmounted.
For advanced users overlay option also supports custom non-volatile `upperdir` and `workdir`
for the overlay mount. Custom `upperdir` and `workdir` can be fully managed by the users themselves
and `podman` will not remove it on lifecycle completion. Example `:O,upperdir=/some/upper,workdir=/some/work`

content, any changes from previous container executions no longer exist.
