Hello Jonathan,

Thank you for the detailed bug report regarding the squashing behavior 
in Podman 5.7.0, and for your follow-up tests confirming the expected 
behavior in version 5.8.0 on Fedora.

Version 5.8.0+ds1-1 is currently available in the experimental suite. 
Could you please test this version against your container source and 
report back to confirm if it resolves the issue on Debian?

Regards,
