`podman-clean-transient.service` is missing for rootless

^{Originally posted by MartinX3 April 9, 2024} I saw that the podman-clean-transient.service only exists in the system folder but not in the user folder.
Doesn't it work in the rootless mode or was it just forgotten?

transient_store is true by default.
