Previously, upgrading Podman containers with the same tag left behind dangling images, causing overlay storage to grow and fill disk space. This change ensures dangling images are cleaned up using podman image prune. The command is run without -a, so only unreferenced images are removed. This provides safe cleanup while preventing unnecessary overlay growth. Fixes #1098 Signed-off-by: Richard Alpe <[email protected]>
