This leaks memory associated with 'optional'

How about having an enum

   typedef enum {
     OSINFO_INSTALL_SCRIPT_CONFIG_POLICY_NONE,
     OSINFO_INSTALL_SCRIPT_CONFIG_POLICY_REQUIRED,
     OSINFO_INSTALL_SCRIPT_CONFIG_POLICY_OPTIONAL,
   } OsinfoInstallScriptConfigPolicy;


  OsinfoInstallScriptConfigPolicy;
  osinfo_install_script_get_config_parameter(OsinfoInstallScript *script,
                                            const gchar *config);

Also I'd probably add an API to list all parameters

  GList *
  osinfo_install_script_get_config_parameters(OsinfoInstallScript *script);
