Commands run when handling `RUN` instructions defaults to being run in their own user namespaces, configured using the UID and GID maps. If --userns-uid-map-user is specified, but --userns-gid-map-group is not specified, `podman` assumes that the specified user name is also a suitable group name to use as the default setting for this option. **NOTE:** When this option is specified by a rootless user, the specified mappings are relative to the rootless user namespace in the container, rather than being relative to the host as it is when run rootful.
