In certain environments like HPC (High Performance Computing), users cannot take advantage of the additional UIDs and GIDs from the /etc/subuid and /etc/subgid systems. However, in this environment, rootless Podman can operate with a single UID. To make this work, set the `ignore_chown_errors` option in the /etc/containers/storage.conf or in ~/.config/containers/storage.conf files. This option tells Podman when pulling an image to ignore chown errors when attempting to change a file in a container image to match the non-root UID in the image. This means all files get saved as the user's UID. Note this could cause issues when running the container.
