[Error] Exported programs not killed if tracked by launch PID

[parkerlreed]

Describe the bug

If a script launches an exported program and tracks the PID with $! , this PID belongs to sh executing the export script and not the real program.

To Reproduce

1. Setup container
2. Install PHP in container
3. distrobox export /usr/bin/php
4. On the host side

#!/bin/bash
~/.local/bin/php &
PID="$!"
kill $PID

The sh script is killed but /usr/bin/php continues to run in the distrobox container.

Expected behavior

Either the script passing on the real PID or killing the script also killing the process within the container.

Desktop (please complete the following information):

• Podman rootless
• Podman 4.2.1
• Distrobox 1.4.2.1
