Hi Bruce
     I didn't mean to change the image-oci.bbclass but to fix the  recipes-extended/images/container-app-base.bb<http://container-app-base.bb>


The answer is the same. There's multiple stacks on top of that example that expect the current behaviour, so I prefer to leave it as-is,
but I can do some testing and see if anything breaks.

The container-app-base is intended to be extended for actual applications, those are just placeholders.

     To make OCI_IMAGE_CMD as empty in container-app-base.bb<http://container-app-base.bb>, or it will have a wrong runtime result as following.
               $ podman run --rm f0d79291ef08
              date: invalid date '/bin/sh'

     Maybe a patch like this?
diff --git a/recipes-extended/images/container-app-base.bb<http://container-app-base.bb> b/recipes-extended/images/container-app-base.bb<http://container-app-base.bb>

     What do you think about it?

Hi Bruce
     I found an issue about OCI_IMAGE_CMD ?= "/bin/sh" when I use the container-app-base image.

    $ podman run --rm f0d79291ef08
     date: invalid date '/bin/sh'

    The issue was caused by the Entrypoint and Cmd are both defined, and cmd will be the append args of date,
    Which caused the output error.

   $ podman inspect f0d79291ef08
      ...
          "Config": {
               "Entrypoint": [
                    "date"
               ],
               "Cmd": [
                    "/bin/sh"
               ],
    ...

   I think make OCI_IMAGE_CMD as empty can solve this issue, what do you think about it?
   OCI_IMAGE_CMD ?= ""

Nope. You can override that yourself.

The current defaults have been extensively tested and modified just recently to make the entrypoint work in more scenarios.

Check git history for all the details.
