Container - adopt user id 1000 instead of 999

Hi! With Podman, under Debian it is required to:

• provide a "home" host directory with 777 permissions or
• adopt the mapping of 999 user (rendercv) [-u rendercv --userns=keep-id:uid=999,gid=999]

Would be instead possible to compile the container using directly the most used user 1000 instead? This would probably simplify the user's topic.

More over, such parameter (userns) has some issues with podman-compose, making impossible to use the compose.yaml files.

Would be possible to adopt uid 1000 for rendercv user inside the container?
