This involves running toolbox(1) itself, and hence validating the subordinate user and group ID ranges. Unfortunately, some build environments, like openSUSE's, don't have subordinate ID ranges set up. Therefore, it's better to not validate the subordinate ID ranges when generating the shell completions, since they are generated by Cobra itself and subordinate ID ranges are not involved at all. Note that subordinate ID ranges may be needed when the generated shell completions are actually used in interactive command line environments. The shell completions invoke the hidden '__complete' command to get the results that are presented to the user, and, if needed, the subordinate ID ranges will continue to be used by podman(1) as part of that.
