podman-system-check - Man Page

When attempting to remove damaged images, also remove containers which depend on those images.  By default, damaged images which are being used by containers are left alone.

Containers which depend on damaged images do so regardless of which engine created them, but because podman only "knows" how to shut down containers that it started, the effect on still-running containers which were started by other engines is difficult to predict.

When considering layers which are not used by any images or containers, assume that any layers which are more than duration old are the results of canceled attempts to pull images, and should be treated as though they are damaged.

Skip checks which are known to be time-consuming.  This will prevent some types of errors from being detected.

Remove any images which are determined to have been damaged in some way, unless they are in use by containers.  Use --force to remove containers which depend on damaged images, and those damaged images, as well.
