[Podman] CMD file not found

Hi, I'm just exploring podman and buildah, but noticed something weird; not sure if it could be a bug or misconfiguration. But I don't know where to look for clues as to what is happening. Sometimes when I start a container I get a file not found error message and then 2 seconds later it starts and runs just fine. What could be the problem? Thanks for any suggestions. (This is a container running Fedora 30) [bkelly@zbox ~]$ podman container start syncthing Error: unable to start container "syncthing": time="2019-07-04T07:23:41Z" level=error msg="container_linux.go:346: starting container process caused \"exec: \\\"/startup.sh\\\": stat /startup.sh: no such file or directory\"\n" container_linux.go:346: starting container process caused "exec: \"/startup.sh\": stat /startup.sh: no such file or directory" : OCI runtime error [bkelly@zbox ~]$ podman container start syncthing syncthing
