createRuntime not getting "bundle" path

[arnej27959]

I'm trying to use a createRuntime hook, but it's not getting the "bundle" path in input.
Normally the input contains something like
"bundle": "/var/lib/containers/storage/overlay-containers/51c44da9ee097e65d48c03208346ec1b396c4c58b99aa50f513dbd3a6d835927/userdata",
but in my setup I'm just getting this:

{
  "ociVersion": "1.0",
  "id": "1975b4da6dcf504d3d3507502ff9a780d45a2dd10246e609f8c2cc6ca918541c",
  "pid": 65910,
  "root": "/var/tmp/intermediate-mountpoint-0.0",
  "bundle": "/",
  "status": "created",
  "annotations": {
    "io.container.manager": "libpod",
    "io.podman.annotations.userns": "private",
    "org.opencontainers.image.stopSignal": "15",
    "org.systemd.property.KillSignal": "15",
    "org.systemd.property.TimeoutStopUSec": "uint64 10000000"
  }
}

To trigger the problem I have found there must be a "deviceNodes" setup, and in addition use of uid mappings.
The commands I'm using are

sudo podman create --name test-pod --uidmap 0:100000:65536 --device mytest/hook=run almalinux:9
sudo podman start test-pod

A minimal /etc/cdi/mytest.yaml looks like this:

---
cdiVersion: 0.5.0
kind: mytest/hook
devices:
    - name: run
      containerEdits:
        hooks:
            - hookName: createRuntime
              path: /tmp/my-hook.sh
              args:
                - my-hook.sh
                - createRuntime 1
containerEdits:
    deviceNodes:
        - path: /dev/tty12

and the script /tmp/my-hook.sh just contains some simple logging to be able to observe the state input:

#!/bin/sh
input=$(cat)
(
	echo "==="
	echo "Running $0 with args: $*"
	echo "Current diretory: $(pwd)"
	echo "Input was: $input"
	echo ">>> formatted >>>"
	echo "$input" | jq .
	echo "<<< formatted <<<"
	echo "==="
	echo ""

) > /tmp/hooks.log 2>&1

This should hopefully make it simple to reproduce.
