The user record should be the source of truth for the user's environment variables, and the user should be able to override them in much the same way that they can if they simply append the variable to their ~/.profile For example, before $LANG would never get set to the user's preferred language, because the service manager always ensures that $LANG is set to something (either the localed config, or a compiled-in default). Thus the user's preferredLanguage setting was always ignored
