Currently, the function will simply fail if ancillary fds are not provided, for ex on unsupported platforms. This changes the failure from: {"error": {"class": "GenericError", "desc": "No file descriptor supplied via SCM_RIGHTS"}} to: {"error": {"class": "CommandNotFound", "desc": "The command getfd has not been found"}} Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Markus Armbruster <armbru@redhat.com>
